Two types of cavities for side pumped Nd:YAG laser mode-locked by semiconductor saturable absorber mirror

Two types of laser cavities for mode locked solid-state laser are designed based on transmission matrix ABCD of line-style resonator and z-style resonator. By adopting these two type of cavities, mode locked Nd: YAG laser side-pumped by diode laser was realized with semiconductor saturable absorber mirror. The highest output power is 1.5 W with the repetition rate of 250 MHz in the line-style cavity. In the z-style cavity, the highest output power is 1 W, and the repetition rate is about 100 MHz with the pulse duration of 200ps.
