Abstract—We reported the Q-switched Ho:YAlO₃ laser with a volume Bragg grating pumped by the Tm doped
fiber laser. The Ho:YAP laser maximum output energy was 1.04 mJ under the repetition frequency of 5 kHz
when the incident power was 12.49 W with the threshold of 2.38 W. The Ho:YAP output wavelength was cen-
tered at 2117.9 nm with bandwidth of about 0.3 nm. The pulse width is 23.9 ns.
