DYNAMIC SIMULATION OF A PHOTOCONDUCTIVE SWITCHING EXPERIMENT

Improved modelling of photoconductive switching experiments can be obt ained by embedding a bipolar ensemble Monte Carlo model of the photoco nductive gap into a time domain solution of Maxwell's equations. In ad dition to making fewer assumptions than previous models, this techniqu e allows for the simulation of a probe pulse used in pump and probe ex periments. Thus it is possible to accurately simulate the entire exper iment and plot the quantity actually observed in the experiments-the p hase shift of the probe beam.
