Paper Abstract

Femtosecond pulse have an appreciable spectral width and it is not possible to satisfy the phase matching condition for all the possible frequency components in the spectrum. This allows pulse propagation with a group velocity that differs from the phase velocity. The difference in the group velocity between the fundamental and harmonic radiation complicates the second harmonic generation. In this paper, the characteristics of SHG from femtosecond optical pulse are discussed. Analytical solutions for the harmonic pulse shape and conversion efficiency in non-depletion condition are presented. In time domain coupled equations in general condition are solved by numerical method. Phase mismatching effect on the harmonic pulse shape and conversion efficiency is analyzed.
