In order to investigate splitting properties of YVO4 Wollaston prisms, by analysis of wave propagation in the prism, the formulas of o beam and e beam at normal incidence were obtained. The curve of splitting properties of the prism changing with wavelength and structure angle was obtained by MATLAB software. The results show that for the prism with the given structure angles, the dispersion property of splitting angle is evident. The shorter the wavelength, the greater the splitting angle, the faster the change. In infrared region, the effect of incident wavelength on splitting angle reduces and splitting angle is stable. The effects of wavelength changes on the symmetry of splitting angle are so little that they can be ignored in the application. The structure angles of the prism and the incident light wavelength have effects on the transmission ratio of prism. For the given structure angles of prism, transmission ratio changes with the wavelength of incident light oscillatory. Spectral effects of o light transmission ratio are more obvious. The research provides an important and valuable reference to the design and application of YVO4 prisms.

Abstract: In order to investigate splitting properties of YVO4 Wollaston prisms, by analysis of wave propagation in the prism, the formulas of o beam and e beam at normal incidence were obtained. The curve of splitting properties of the prism changing with wavelength and structure angle was obtained by MATLAB software. The results show that for the prism with the given structure angles, the dispersion property of splitting angle is evident. The shorter the wavelength, the greater the splitting angle, the faster the change. In infrared region, the effect of incident wavelength on splitting angle reduces and splitting angle is stable. The effects of wavelength changes on the symmetry of splitting angle are so little that they can be ignored in the application. The structure angles of the prism and the incident light wavelength have effects on the transmission ratio of prism. For the given structure angles of prism, transmission ratio changes with the wavelength of incident light oscillatory. Spectral effects of o light transmission ratio are more obvious. The research provides an important and valuable reference to the design and application of YVO4 prisms.
