Abstract

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:YVO4 crystal. An AO Q-switched dual-rod Nd:YVO4Nd:YVO4 laser was also configured for comparative investigation. A 69 and 75W near diffraction-limited laser in CW operation was obtained for the dual-rod Nd:YAGNd:YVO4 laser and dual-rod Nd:YVO4Nd:YVO4 laser, respectively. In the Q-switched operation, 500kHz output with 64.2W average power and 650kHz laser with 73.2W average power was achieved for the Nd:YAGNd:YVO4 laser and Nd:YVO4Nd:YVO4 laser, respectively. The detailed comparison on the performance of pulse duration, pulse repetition rate, output power, and optical spectrum was also investigated and discussed.
