Self-mode-locking semiconductor disk laser

Open Access Open Access

Abstract

The development of mode-locked semiconductor disk lasers received striking attention in the last 14 years and there is still a vast potential of such pulsed lasers to be explored and exploited. While for more than one decade pulsed operation was strongly linked to the employment of a saturable absorber, self-mode-locking emerged recently as an effective and novel technique in this field – giving prospect to a reduced complexity and improved cost-efficiency of such lasers. In this work, we highlight recent achievements regarding self-mode-locked semiconductor devices. It is worth to note, that although nonlinear effects in the active medium are expected to give rise to self-mode-locking, this has to be investigated with care in future experiments. However, there is a controversy whether results presented with respect to self-mode-locking truly show mode-locking. Such concerns are addressed in this work and we provide a clear evidence of mode-locking in a saturable-absorber-free device. By using a BBO crystal outside the cavity, green light originating from second-harmonic generation using the out-coupled laser beam is demonstrated. In addition, long-time-span pulse trains as well as radiofrequency-spectra measurements are presented for our sub-ps pulses at 500 MHz repetition rate which indicate the stable pulse operation of our device. Furthermore, a long-time-span autocorrelation trace is introduced which clearly shows absence of a pedestal or double pulses. Eventually, a beam-profile measurement reveals the excellent beam quality of our device with an M-square factor of less than 1.1 for both axes, showing that self-mode-locking can be achieved for the fundamental transverse mode.

1. The path to self-mode-locking

Semiconductor disk lasers (SDLs), also known as vertical-external-cavity surface-emitting lasers (VECSELs), are versatile lasers which serve as an excellent platform for the realization of various emission schemes. The first of its kind was demonstrated in 1997 by Kuznetsov et al. [1] and thereafter - owing to their remarkable design flexibility and features – rise was given to a plethora of modifications and improvements towards more specific applications. In recent years, not only high-power multi-mode [2] or single-frequency [3] continuous-wave operation schemes have been achieved, but also two-color [4] as well as mode-locked [5] emission. Particularly, their external resonator is predestined to be exploited for intra-cavity frequency conversion via nonlinear elements which expands the accessible wavelength range drastically. While second-harmonic generation pushes the boundaries into the UV [6], even terahertz frequencies can be reached using difference-frequency generation inside a two-color VECSEL [7, 8] - to name a few remarkable achievements in this field.

Within the last decade, VECSELs have become particularly appealing sources of pulsed laser light, because they can typically provide a high output power and an outstanding beam quality. The demonstration of the first mode-locked (ML) VECSEL dates back to the year 2000 and was achieved by Hoogland et al. for a central wavelength of 1 µm with 22 ps long pulses [9]. It did not take long and VECSELs were considered becoming compact, cost-efficient alternatives to commercial mode-locked lasers with ever shorter pulses, higher peak powers and enhanced tunability using resonator-integrated [1030] or even chip-integrated [31, 32] semiconductor saturable-absorber mirrors (SESAMs). However, the complex, power-sensitive and costly SESAMs, which have to be carefully designed for a certain wavelength range, naturally impose limitations on the performance of the device. Currently, besides semiconductor materials, graphene [33, 34] as well as carbon nanotubes [35] saturable absorbers have been employed for ML operation of VECSELs. However, mode-locking has also been reported to take place even without any additional saturable absorber—an effect called self-mode locking (SML) [3641].

In this work, light is shed on recent demonstrations of SESAM-free VECSELs which are operated under SML conditions. It was recently demonstrated that the SML scheme is not only applicable to quantum-well VECSELs [3639, 41], but also to quantum-dot devices [40]. Furthermore, SML can be used for passively harmonically mode-locked devices with sub-ps-pulsed operation demonstrated at discrete power levels up to the third harmonic [39]. Inherently, this novel and effective technique allows for a maximum degree of wavelength flexibility and a reduction of device complexity. However, the mechanism of SML, which could give access to an exhaustive utilization of the occurring effects, is not fully understood yet and will be subject to future studies - noting that different driving mechanisms for SML were proposed [3638, 41]. Nevertheless, an optimization of the dispersion management as well as the thermal management in an optimistic view promises the achievement of shorter pulses in the sub-100-fs range and significantly higher peak powers exceeding the current values at repetition rates ranging from a few hundreds of MHz to a few GHz.

In Fig. 1, an overview of all mode-locking techniques of optically pumped VECSELs around a wavelength of 1 µm is shown. More details and the attribution of numbers to references can be found in Table 1.

Yet, the mode-locking semiconductor-laser community doubts that previous publications about SML truly show mode-locked devices. In our work, we intend to address concerns that have been discussed recently. Most prominent is the discussion presented in Refs [42, 43] triggered by a report on SESAM-free ML-VECSEL [37]. In the following, we provide clear evidence of SML by a variety of measurements: Green light originating from second-harmonic generation using the out-coupled laser beam is observed when our device is running in the ML regime. Furthermore, by presenting long-time-span pulse trains as well as radiofrequency-spectra measurements for our sub-ps pulses at 500 MHz repetition rate we highlight the stability of our device. In addition, a long-time-span autocorrelation trace shows absence of a pedestal or double pulses. Finally, we show a beam-profile measurement which reveals the excellent beam quality of our device with an M-square factor of less than 1.1 for both axes.

2. VECSEL chip design and setups

The VECSEL chip used in our experiments is grown by metal-organic-vapour-phase-epitaxy. The gain medium consists of 10 (InGa)As quantum wells (QWs) equally spaced by λ/2 GaAsP barrier layers. 24½ pairs of quarter wavelength GaAs/AlGaAs layers form a distributed Bragg reflector (DBR). Both, QWs and DBR are designed for a laser emission at approximately 1010 nm. The semiconductor structure is flip-chip-bonded using Au-In solid-liquid inter-diffusion bonding onto a 350 µm thick CVD-diamond heat spreader before wet etching to remove the substrate.

An anti-resonant micro-cavity design is chosen in order to minimize the group delay dispersion (GDD) and to spectrally broaden the effective gain of the structure. Therefore, the (InGa)P cap layer is etched down to a thickness of 1.25*λ/4, which theoretically results in a negligible GDD at the design wavelength. The electric-field (E-field) distribution inside the gain medium is shown in Fig. 2(a). The positions of the quantum wells are represented by the vertical red lines. The laser setup is schematically shown in Fig. 2(b): The cavity is optimized for mode-locked operation assuming Kerr-lensing inside the VECSEL chip structure [38]. Therefore, a variable slit is placed directly in front of a highly reflective end mirror (HR). The Z-shaped cavity consists of a flat output coupler (OC) with a transmittance of 1.6%, the gain chip itself, and a highly reflective curved mirror (CM) with a radius of curvature of 150 mm as well as the HR mirror. With a total cavity length amounting to 30 cm a free spectral range of approximately 0.5 GHz is determined. The laser chip is mounted onto a water-cooled copper heat sink and pumped under an incident angle of 30° using an 808 nm fiber-coupled diode laser which is focused onto the chip and ensures a pump mode of adjustable size. The angle of incidence on the curved mirror was kept below 10° in order to avoid excessive astigmatism.

3. Evidence of self-mode-locked operation

In our VECSEL, mode-locking is initiated when the slit in front of the HR end mirror is moved or the slit width is narrowed. Furthermore, the cavity length was fine-tuned to stabilize SML operation (cf [39, 40].). In order to clearly demonstrate mode-locked operation employing the SML technique, different measurements have to be carried out [42]. Usually radiofrequency (RF) spectra, optical spectra, autocorrelation traces are sufficient for the characterization of mode-locking operation. However, if a new mode-locking technique is introduced, further measurements are required in order to exclude artificial effects and the standard characterization methods cannot serve as an unambiguous evidence of mode-locking. One of these artificial effects that could give the impression of a ML device is mode-beating which could result in an RF spectrum similar to which is recorded with a ML device. This was clearly demonstrated in [42]. Moreover, an autocorrelation trace can also be misleading as a CW signal may result in a time trace which gives rather information about the coherence length than about a pulse duration [44]. The possibility that both RF spectra and autocorrelation traces, which are presented in the next section, are misapprehended can be banned by recording externally the second-harmonic generation (SHG) signal of our SML-VECSEL.

A nonlinear frequency conversion in a BBO crystal is performed using an SML VECSEL for the first time, to the best of our knowledge. Therefore, the out-coupled laser beam of the VECSEL is directed into the nonlinear crystal, as seen in Fig. 3, so that green light is externally produced via SHG with the infrared pulsed laser light. In case of continuous-wave operation no SHG signal is observed whereas a clear spectrum of the SHG signal can be measured if the laser is mode-locked, since SHG is an intensity-dependent nonlinear effect. The top inset of Fig. 3 shows the corresponding spectrum of the frequency-doubled signal (507 nm) originating from SHG using the out-coupled SML VECSEL beam (1013 nm). The photo shown in Fig. 3 presents the actual setup used for this experiment with colored dotted lines indicating the beam path inside and outside the VECSEL. The slit is highlighted by flash light and is placed directly in front of the HR mirror of the cavity. A lens is used to focus the VECSEL output into the nonlinear crystal, as shown in the left part of the photo.

To highlight stable mode-locked operation of our QW VECSEL, a representative long-span pulse-train of the output is shown as inset on the bottom of Fig. 3. The signal was recorded for both a time window of 20 μs (bottom-left) and a few ns (bottom-right), respectively, via an InGaAs photodetector (PD) with a 3 dB bandwidth of 5 GHz and a digital oscilloscope with an analog bandwidth of 2 GHz. Stable mode-locking can be derived from this measurement as the pulse train with approximately 500 MHz repetition rate exhibits no intensity modulations.

4. Characterization of the emission features

In this section, we present RF-spectra measurements as well as time-resolved autocorrelation data of a VECSEL operated under SML conditions. Moreover, a beam-profile measurement is performed in order to reveal the excellent beam-quality of our device. Since RF-spectra measurements provide information on the frequency stability of the generated pulses, measurements are performed with a 3-dB bandwidth of a 5-GHz PD coupled to a 22-GHz-bandwidth electrical spectrum analyzer (HP 8566A). Figure 4 shows the RF spectrum of the fundamental repetition rate measured using a 10 kHz resolution bandwidth (RBW). Here, a clear peak at 504 MHz with a signal to noise ratio of about 50 dB is observed. The RF linewidth is less than 30 kHz, which highlights the stable operation of our mode-locked system. This result is similar to those obtained from SESEAM mode-locked VECSELs [12, 27]. The inset of Fig. 4 presents the RF spectrum of the first 9 harmonics indicating a stable pulse generation with no parasitic sidebands around the fundamental and higher harmonics frequencies.

The mode-locked pulse duration was measured with a self-made intensity autocorrelator with a scan range of ~130 ps. Figure 5(a) shows a long-delay autocorrelation trace for fundamental mode-locking confirming the single-pulse operation. To complement the information, a short-delay autocorrelation trace with sech2-fit is shown in Fig. 5(b) which yields a pulse duration of 860 fs. The corresponding optical spectrum was measured using an Ando AQ-6315A optical spectrum analyzer. The spectrum has a full width at half maximum of 2.7 nm, resulting in a time bandwidth product (TBWP) of 0.68 (Fig. 5(c)). The average output power was measured to be 460 mW for this QW VECSEL which leads to a peak power of 950 W.

Finally, the beam quality was measured for an average output power of 450 mW, see Fig. 6: Excellent M-square values of 1.07 and 1.08 in the horizontal and vertical directions respectively have been obtained, confirming lasing in the fundamental transverse mode with nearly ideal Gaussian characteristics. The inset shows a corresponding beam-profile under SML operation. While Liang et al. [41] supposed that the occurrence of SML can be assisted by the existence of high-order transverse modes, our results are in contrast to these findings. Liang et al. observed a threshold for SML which coincided with the threshold of high-order transverse modes. With our results we rule out a dependence of SML on high-order transverse modes and demonstrate an excellent beam quality of our SML VECSEL with fundamental-transverse-mode profile.

5. Conclusion

To summarize, we highlighted recent achievements in the field of ML and in particular SML VECSEL and presented a clear evidence of mode-locking for a QW device under SML conditions. Green light originating from second-harmonic generation in an external BBO crystal was demonstrated using the out-coupled laser beam. In addition, long-time-span pulse trains as well as radiofrequency spectra measurements were presented for our sub-ps pulses at 500 MHz repetition rate which indicate the stable pulse operation of our device. Furthermore, a long-time-span autocorrelation trace, which emphasizes the absence of a pedestal or double pulses, was shown. Additionally, a beam-profile measurement revealed the excellent beam quality of the device with an M-square factor of less than 1.1 for both axes. Even though the driving mechanism for SML has to be studied with care in future investigation for an efficient use of the underlying effects, we believe that in the near future SML VECSELs, which combine the advantages of solid-state and semiconductor devices, can become robust, compact and low-cost sources of fs-pulsed laser light.
