Abstract

Based on Fresnel diffractive theory, a binary optical laser cavity is designed for a circle, flat topped fundamental mode. Instead of the traditional spherical mirrors for a laser cavity, the diffractive mode-selecting mirrors are used to optimize the amplitude and phase of the laser mode by simulated annealing algorithm. The computer simulation results show that the mode loss rate between TEM₀₀ and TEM₀₁ is 1:430 for a round trip in the cavity, and only the required fundamental mode is established in the laser cavity.
