Abstract

The Ti:sapphire-pumped optical parametric oscillator (OPO) based on noncritically phase-matched LiB₃O₅ (LBO) is a versatile source of high-repetition-rate picosecond pulses for the near-infrared.¹ It is capable of providing signal and idler output pulses with durations of 1-2 ps over the continuous wavelength range 1-2.5 µm at hundreds of milliwatts of average power. We have now extended the spectral coverage of the device to the visible region by intracavity frequencydoubling the OPO signal pulses to provide transform-limited 840-fs pulses in the 584-771-nm range, with average powers as high as 320 mW.
