Simple Model for Calculating Photoionization Rate in AVLIS System-1. Photoionization in Resonant Medium.

A simple model for calculating the photoionization rate in AVLIS system is proposed. It was found that, forthe different incident laser conditions, the dependence of photoionization rate of target atom on the propagation distance estimated by the model represents well the simulation result. It has been confirmed that thismodel is useful for analyzing the performances of AVLIS plant without simulation.
