| Abstract: | A high efficiency all-solid-state green laser was reported which was double end-pumped by the laser diode(LD) Nd:YAG, passive Q-switched by Cr4+:YAG, and critical phase matched by LBO intracavity. The thermal effect of double end-pump YAG laser was analyzed. In the experiment, double end-pump of LD is used to conduct the conduction cooling of Nd:YAG with the U-type parallel flat cavity structure. When the input power is 33.8 W, the output power of linear polarized light with 10 kHz passive Q-switch is 8.21 W which leads to the output power instability of 6.72 W and frequency doubling efficiency of 86%. The output beam is the fundamental model and M2 reaches 1.4. The experiments show that the double end-pumped YAG frequency multiplication laser has quite high conversion efficiency. |
