Paper Abstract

A quasi-continuous-wave diode array side-pumped Q-switched Yb:YAG slab laser has been demonstrated. A KD*P crystal is used as an electro-optic Q-switch and 3.07-mJ output energy with a pulse width as short as 56.27 ns (FWHM) is obtained. The Yb:YAG crystal doped density is 10 at.% with the dimension 8×3×1 mm. The pulse width and energy fluctuations are 3.44% and 3.36% respectively. The relative Q-switched theory is analyzed and rate equations are calculated. The influence of Q-switch delay time on pulse performance is also studied. The final experimental results coincide well with the theoretical results.
