Abstract: In this work, we demonstrate an efficient actively Q-switched laser based on a novel crystal Nd:YAG/YAG polygonal active mirror. A passively cooled crystal Nd:YAG/YAG polygonal active mirror with an end pump scheme was used as the gain medium. For the overlap between the TEM00 laser mode and large gain profile, a cavity was carefully designed with a large fundamental mode volume. With a maximum absorbed power of 3.1 W, a 685 mW average output power with a pulse repetition of 5 kHz was attained, and the corresponding optical–optical and slope efficiency were 22.1% and 27.7%, respectively. The pulse width was 133.9 ns. The beam quality (M2) was 1.561 in the horizontal direction and 1.261 in the vertical direction.

Passively Q-switched laser based on Nd:YAG/YAG Polygonal Active Mirror with timing jitter improvement
TL;DR: In this paper, the authors demonstrate a passively Q-switched laser based on PAM, where Cr:YAG with different initial transmittance were used as saturable absorber (SA) to improve the output timing jitter.
