Characteristics of two types of prism resonators used for slab lasers

In this paper, two types of prism resonators, namely, the resonator with a 90 degree(s) prism and a HR/R-coated plane mirror, and the resonator with a 90 degree(s) prism, a triple prism and HR/R mirror, have been studied in detail including: (1) the polarization properties of the prism resonators used for slab lasers were analyzed by means of the Jones matrix calculus and then confirmed experimentally; and (2) numerical calculations of the diffraction integral were performed, using the fast Fourier transform (FFT) method, to illustrate the resonator mode characteristics.
