摘要

We demonstrated an acousto-optically (AO) Q-switched dual-rod laser with different gain crystals in the cavity, the combination of Nd:YAG crystal and Nd:YVO_(4) crystal. An AO Q-switched dual-rod Nd:YVO_(4) - Nd:YVO_(4) laser was also configured for comparative investigation. A 69 and 75 W near diffraction-limited laser in CW operation was obtained for the dual-rod Nd:YAG - Nd:YVO_(4) laser and dual-rod Nd:YVO_(4) - Nd:YVO_(4) laser, respectively. In the Q-switched operation, 500 kHz output with 64.2 W average power and 650 kHz laser with 73.2 W average power was achieved for the Nd:YAG - Nd:YVO_(4) laser and Nd:YVO_(4) - Nd:YVO_(4) laser, respectively. The detailed comparison on the performance of pulse duration, pulse repetition rate, output power, and optical spectrum was also investigated and discussed.
