Interactive design of laser electrodes using elliptic grid generation and semidirect/marching methods
Abstract
A computational effort to develop computer codes for rapidly and accurately modeling the electric fields within laser cavities is described. Semidirect/marching methods are used both for the generation of two dimensional boundary fitted grids using the elliptic generating equation approach, and for the solution of electric field problems in those coordinate systems. The efficiency of the semidirect/marching methods makes possible interactive design of the laser electrodes using a modest computer. Also described are techniques for high order accuracy, a method for precise grid control at interior points, and applications to the elliptic grid generation problem of computer symbolic manipulation.
