A Program for Non-Collinear Phase-Matching Applications



N Boeuf, I Chaperot, E Dauler, G Jaeger, Andreas Muller, Alan L. Migdall


This is a program for calculating characteristics of collinear and non-collinear phase matching in both uniaxial and biaxial crystals. In particular, this program calculates the difference of the fast end slow indices of refraction as a function of angle, the indices of refraction as a function of wavelength and signal and idler photon emission angles under phase-matching constraints in various formats.
