| 摘 要： | 报道了一种主要应用于激光测距的微型化激光二极管泵浦Er3+/Yb3+共掺磷酸盐玻璃被动调Q激光器。采用中心波长940nm的二极管作为泵浦源,Er3+/Yb3+共掺磷酸盐玻璃作为增益介质,Co2+:MgAl2O4作为被动调Q晶体,通过优化增益介质和被动调Q晶体参数,获得了最佳的增益介质长度和被动调Q晶体初始透过率。当泵浦能量14mJ,重复频率10Hz,泵浦脉宽5ms时,获得了单脉冲能量480μJ,脉宽5ns,峰值功率大于20kW的激光输出,激光光束质量因子为1.2。

| Abstract: | A miniature diode pumped passively Q-switched Er3+ and Yb3+ co-doped phosphate glass laser is reported. The center wavelength of pump source is 940 nm. A Co2+: MgAl2O4 crystal is used as a saturable absorber. When the pump energy is 14 mJ, stable Q-switched pulses are obtained at repetition frequency of 10 Hz and pump pulse width of 5 ms. The output pulse energy of laser is 480 J and pulse width is 5 ns . The wavelength of laser is 1535 nm. The peak power is higher than 20 kW and beam quality is 1.2. |
