Paper Abstract

The numerical simulation of the short time response, femtoseocond to picosecond regime, of a saturable absorbing material is described. Transient relationships for the intensity and temperature dependent absorption coefficient and index of refraction are included. The thermal response includes a hyperbolic microscale heat transfer mechanism. Initial results are reported for the calculated transmitted intensity, excited state population and temperature field of a slugglish saturable Kerr medium. This short time model can be used to investigate the onset of thermally stimulated nonlinear optical behavior, the "switch on" time, and other short time effects.
