摘要：

A miniaturized, eye-safe laser with wide adaptive temperature is reported. Er3+, Yb3+ co-doped phosphate glass is used as the gain medium. A Co2+: MgAl2O4 crystal is used as the saturable absorber. The miniaturized laser structure suitable for wide temperature range and the output characteristics of the passively Q-switched laser are investigated. The pump energy of 9 mJ, repetition frequency of 10 Hz, pump duration of 5 ms, pulse energy of 130 μJ, pulse duration of 5.5 ns, peak power of 20 kW, and beam quality M2of 1.3 were obtained. The laser structure uses vacuum packaging and can run stably in the temperature range of -40℃ to 50℃. The output instability is less than 5% by natural cooling. The laser can also be driven by lithium batteries for further application. ©, 2015, Editorial Office of High Power Laser and Particle Beams. All right reserved.
