By using a pulse laser at 532.36nm as the incident light,stimulated Raman scattering (SRS) of a series of a-cut and c-cut Nd∶LuxY1-xVO4 (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.
