A method to solve the problems about reflection and refraction on the surface of a biaxial crystal is introduced, which can be applied to calculating refractive index, polarization direction, wave vector, Poynting vector of refracted waves for any direction of incidence and any orientation of major axes. The formulae t o calculate electric amplitude and optical power of each light beam are derived. The results of numerical calculations for a KTP crystal are given.
