Laser Resonator Model-Finite Difference Method
Abstract
Three computer programs are described which allow the study of optical properties of two dimensional laser resonators. Two of the programs treat the propagation of an electric field inside an optical resonator (there are two methods for propagating an arbitrary electric field), and couple the propagating fields to a specified laser medium which may be nonuniform, transversely flowing, saturable, and inhomogeneous. The propagation technique includes diffraction effects throughout the laser medium. Both programs provide output beam characteristics and output power. The third program calculates far field beam characteristics for the laser output. Some of the features offered the user are a restart facility for long runs, arbitrary location of the medium in the resonator cavity, and capacity for mirror tilt on either or both mirrors.
