摘要：

We report on laser diode (LD) pumped passively Q-switched Yb,Gd:SrF2 lasers with high single-pulse energy for the first time, to the best of our knowledge. In addition, a stable Q-switched laser based on a Cr4+:Y3Al5O12 saturable absorber was demonstrated. The maximum output power of the Q-switched laser obtained was 495 mW, with a pulse width and a pulse repetition rate of 233 ns and 1.238 kHz, respectively. The corresponding single-pulse energy and the peak power were as high as 400 mu J and 1.714 kW. The laser was operated under a transverse electromagnetic mode, and the beam quality was near-diffraction-limited.
