Harmonic and supercontinuum generation in quadratic and cubic nonlinear optical media

摘要

We present numerical simulations by means of the generalized nonlinear envelope equation of harmonic and supercontinuum generation induced by femtosecond pump pulses in optical media with both quadratic and third-order nonlinearities. Application examples to higher harmonic generation in periodically poled lithium niobate and optical parametric generation of a mid-infrared continuum in gallium arsenide are discussed.
