Abstract- Producing desirable modes in a laser resonator as a fundamental one and eliminating other modes is common in designing laser resonators to extract more power from gain medium. High modal discrimination achieved by designing a resonator consists of a mode-selecting mirror and an internal phase grating. In this research, we simulate a resonator with a mode-selecting mirror and an internal phase grating by Mathlab software. By this method, higher order modes are eliminated and 20th order Super-Gaussian mode is produced by mode selectingg mirror and remain with minimum loss. By comparing 20th Super-Gaussian and TEM11 modes, optimal frequency for phase grating is obtained by simulating these two modes propagation in resonator.

Keywords: Phase grating, Mode selecting mirror, 20th order Super-Gaussian mode.
