Raman Gain Coefficients of Nd:LuxY1−x VO4 Crystals

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:Lu0.1Y0.9VO4 crystal. Such results are also supported by the measurement of spontaneous Raman scattering spectra.
