【Abstract】 In this paper,the properties of Raman optical crystals are described by taking strontium tungstate（ SrWO₄） crystal as an example. In recent years,a series of pure and rare earth ion doped strontium tungstate（ SrWO₄） crystals were successfully grown by the Czochralski method. The thermal properties of SrWO₄ crystal was obtained. The refractive index of SrWO₄ crystal was tested,and the dispersion equation of refractive index was fitted by using the least square method. The polarized absorption spectra,near infrared polarized fluorescence spectra and fluorescence lifetime curves of Nd∶ SrWO₄ crystal were tested and the spectral parameters were calculated. Nd∶ SrWO₄ crystal has excellent spectral properties. Several laser experiments of SrWO₄ and Nd∶ SrWO₄ crystal were carried out,which contain the raman laser performance of SrWO₄ crystal and the self-raman laser performance of Nd ∶ SrWO₄ crystal. The results show that,SrWO₄ crystal has excellent raman performances.更多还原
