Passively Q-switched multi-wavelength Nd:YVO4 self-Raman laser

Abstract

Multi-wavelength self-Raman laser from a passively Q-switched c-cut Nd: YVO4 laser at 1066.8 nm to four discrete Stokes lines at 1097.2, 1129.2, 1168.3 and 1178.8 nm is demonstrated simultaneously for the first time. With a 0.27 at% c-cut Nd:YVO4 crystal, the total output power of Stokes lines is 267 mW at a pump power of 5.0 W.
