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.
