Abstract
An efficient self-stimulated Raman laser of Nd:LuxY1−xVO4 (x = 0.1, 0.26, 0.41, 0.61, 0.67 and 0.8) series crystals was demonstrated for the first time. Compared to YVO4, 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:Lu0.26Y0.74VO4 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:Lu0.26Y0.64VO4 crystal should be an excellent self-Raman laser material.
