Study of Applicability of Iterative Saturated Gain Model in Confocal Unstable Resonator Analysis

摘要

An existing method of calculating the eigenmodes of confocal unstable strip resonators is reviewed. This method has the advantage of accurately accounting for diffraction effects but is limited to inclusion of an arbitrary symmetric gain distribution. An extension of this method to include a realistic saturated gain distribution is proposed. This gain distribution is calculated numerically by using an iterative technique to arrive at a self-consistent solution for both the gain and field distributions. Several appendicies are presented to aid in understanding the basic theory. (Author)
