|Abstract:||The temporal and spectral distributions of cascade third harmonic generation in a quasiperiodical optical superlattice were presented. Pulse shaping and integrated energy conversion were studied for both input transform-limited and chirped pulses, and for both phase matched and phase mismatched configurations. The phase mismatch between the center frequencies of the fundamental and harmonic pulses and the group velocity mismatches (GVM) among the interacting pulses were studied. The pulse shaping features were observed and was found to consist of a multiplicity in phase and and amplitude. The phenomena in harmonic energy conversion, which provide more flexibility for harmonic generations in the ultrashort pulse range were also analyzed.|
