ANALYTICAL MODEL FOR SECOND-ORDER CASCADED EFFECT WITH A LINEAR CHIRPED GAUSSIAN PULSE

摘要

In this communication we report the type I second-order non-linear interaction of fundamental and second- harmonic fields in a non-linear crystal in a non-stationary condition with a linear chirp superimposed on a Gaussian pulse. This last pulse shape allows an analytical solution even with a linear chirp while the simple sech pulse shape input without the chirp was not.
