In this paper, The output beam of a Nd:YAG laser resonator with a Gaussian mirror as an output coupler is simulated using ABCD matrix method and Collins diffraction integral. For this purpose, the beams propagation inside resonators for different round-trips is studied and by considering suitable transmission function for output coupler, the transverse profile of output beam is obtained. The results show that, the output beam profile depends on the resonator parameters and is stable after several round-trip.
