With a laser-diode (LD) as the pump source, continuous-wave (cw) laser performance at 1.33 µm of Nd:CNGG and Nd:CLNGG crystals was demonstrated for the first time. The maximum power of 158 mW and 141 mW from Nd:CNGG and Nd:CLNGG lasers were obtained with the corresponding optical conversion efficiencies of 1.3% and 1.5%, and slope efficiencies of 2.0% and 2.9%, respectively. The difference between the laser performance of Nd:CNGG and Nd:CLNGG crystals was also discussed.Intensity, a.u.

Laser-diode pumped continuous-wave (cw) laser performance of a new class Nd:LuxGd1-xVO4 crystals at 1.34 μm was demonstrated for the first time to our knowledge. A maximum output power of 2.25 W was obtained at the incident pump power of 11.96 W with x = 0.14, giving the corresponding optical conversion efficiency of 18.8%. Efficient emission cross-sections of the mixed crystals were calculated for different x. The influence of Lu composition x on the variations of laser performance and emission cross-section was also discussed.

An efficient self-stimulated Raman laser of Nd:Lu x Y 1−x VO 4 (x = 0.1, 0.26, 0.41, 0.61, 0.67 and 0.8) series crystals was demonstrated for the first time. Compared to YVO 4 , the relative Raman gain coefficients were determined by studying their spontaneous Raman scattering spectra. With the largest thermal conductivity, excellent energy storage capability and moderate Raman gain coefficient, the Nd:Lu 0.26 Y 0.74 VO 4 crystal presented the best Raman laser performance: 2.3 W average output power, 71 µJ single pulse energy and 26.3 kW peak power. The results indicated that the Nd:Lu 0.26 Y 0.64 VO 4 crystal should be an excellent self-Raman laser material.
