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