Abstract
The matrix eigenvalues method is used to analyze the laser cavity in which the traditional spherical mirror is replaced by the phase type diffraction optical elements. The authors analyze, the characteristics of the modes und er the conditions of different Frenesl number. The results show that this l aser cavity can enhance the discrimination between spatial modes effectivel y and can be used to design the output laser beam.
