Abstract ：By using a pulse laser at 532.36 nm as the incident light, stimulated Raman scattering (SRS) of a series of a-cut and c-cut Nd:Lux 1?x VO4 (x =0, 0.10, 0.26, 0.41, 0.61, 0.67, 0.80) crystals is investigated. For the π -polarization (E||c ), the gain coefficient reduced as x value increased. For the σ -polarization (E||a ), the Raman gain of all of the mixed crystals is larger than the pure Nd:YVO4 , and the maximum value is obtained from the Nd:Lu0.1 Y0.9 VO4 crystal. Such results are also supported by the measurement of spontaneous Raman scattering spectra.
