•Laser characteristics under acousto-optic Q-switched operation of 1319 nm/1338 nm were studied.•Maximum pulse output power of 5.2 W, maximum peak power of 3.96 kW, and minimum pulse width of 65.6 ns.•The duty ratio of ultrasonic signal should be proper. The duty ratio could not be too high to block the laser oscillation.
Laser characteristics of acousto-optic Q-switched operation of 1319 nm/1338 nm dual-wavelength composite Nd:YAG laser were studied. Maximum output power of 5.77 W was achieved in CW operation. Under Q-switched operation, the maximum peak power of 3.96 kW and minimum pulse width of 65.6 ns was obtained at repetition frequency of 20 kHz with the duty ratio of 96%. The influence of the duration of the ultrasonic field acted on the Q-switch to the output characteristics of dual-wavelength composite Nd:YAG laser had been reported first time.
