Abstract
System of evolution equations describing ultra-short optical pulse propagation in quadratic non-linear medium is derived with taking into account the dispersion of the non-linear susceptibility and second-order group-velocity dispersion. Both type I and type II of phase matching were considered. The case of a finite phase mismatch was analyzed by an analytical method. The steady state pulses of the fundamental and second harmonic waves were found. There are new kinds of ultra-short pulses propagating in quadratic medium in the anomalous and normal dispersion regime.© (2001) COPYRIGHT SPIE--The International Society for Optical Engineering.
