摘要

We demonstrate a high-repetition-rate millijoule passively Q-switched eye-safe Nd:YVO 4 laser pumped by a quasi-CW diode stack. A theoretical analysis has been explored for the design criteria of generating TEM n , 0 mode in the diode-stack directly side-pumping configuration. We successfully generate TEM n , 0 modes at 1064 nm by adjusting the gain medium with respected to the laser axis. We further observe the spatial cleaning ability for generating an nearly TEM 0 , 0 mode output at 1573 nm with a monolithic OPO cavity. At the repetition rate up to 200 Hz, the output pulse energy reaches 1.21 mJ with the threshold pump energy of 17.9 mJ.
