Numerical simulations of optical parametric amplification cross-correlation frequency-resolved optical gating

摘要

We perform numerical simulations of cross-correlation frequency-resolved optical gating with the nonlinearities, optical parametric amplification, and difference-frequency generation for measuring broadband pulses. We show that use of a noncollinear beam geometry that matches the group velocities of the pump, signal, and idler pulses permits use of relatively thick crystals for high gain without significant distortion in the measured trace yielding bandwidths of similar to 100 nm.
