Abstract
Recently diode-pumped Nd-doped lasers have been developed as compact all-solid-state source in the blue, green, and red spectral regions with intracavity frequency doubling. However, the region between 550 and 650 nm is seldom covered by these sources because of the absence of efficient fundamental lasers. Laser sources in the yellow-orange spectra are particularly of interest for a lot of applications in medicine, biology, and display technology.1 One approach for generating cw yellow-orange laser output is to use sum frequency mixing (SFM). Although this approach has previously been efficiently obtained with a resonant external cavity, 2 it suffers from the disadvantages of much greater complexity and higher cost compared with single-pass extracavity SFM.3,4 In this work, we demonstrated compact efficient cw yellow laser generation from single-pass SFM of a diode-pumped Nd:YVO4 dual-wavelength laser with a periodically poled lithium niobate (PPLN). A three-mirror linear cavity was proposed to generate stable simultaneous cw emission of two wavelengths, which λ, is 1342 nm and the other λ2 is 1064 nm, from a diode-end-pumped Nd:YVO4 laser.
