| Abstract: | We report a LD side-pumped fundamental-mode (Mx2 = 1.35 and My2 = 1.27) passive Q-switched and mode-locked Nd:YAG laser based on a semiconductor saturable absorber mirror (SESAM). At a
pump current of 12.5 A, the average output power of 5.68 W with 80 kHz repetition rate and 2 μs pulse width of the Q-switched
envelope was generated. The repetition rate of the mode-locked pulse within the Q-switched envelope of 88 MHz was achieved. |
