Computer graphics simulation for transverse mode building-up process in laser resonator

The amplitude and phase distributions of the optical field in a laser resonator(stripped resonator)are numerically calculated on IBM-PC based on the Frensnel-Kirchhoff diffracted integral equation,and the results are displayed as a dynamic process of the transverse mode building-up by a three-dimensional graphics expression.The numerical calculation results and the graphs are in agreement with the results given by Fox and Li.Thus,a new CAD for laser resonator is presented.
