In order to develop a field distribution program that resolves the model of stable resonator any cavity,the phase model of the cube comer prism is established using continuously the law of reflection of ray vector. A mathematical model of the oriented prism laser field distribution is developed at first. A field distribution program that resolves the model of stable resonator in any cavity is developed. And the modes of stable resonator consisting of directional prism are investigated with FOX-LI iterative method. The amplitude and phase distributions of the output mirror are presented.In the experiment,the avoidance adjust solid state laser is used. Both the experimental results about the output near-field speckle of laser, far-field speckle of laser and the result from the laser beam quality analyzer are compared with 3-D numerical simulation.The simulation results are in agreement with experimental results.A good effect is obtained in practical application.
