| 中文摘要 | 报道了一种小型宽温Nd∶YAG激光器及掠入射式放大器。采用Nd∶YAG类光纤晶体作为增益介质,采用垂直腔面发射半导体激光器(VCSEL)阵列作为抽运源,利用Cr~(4+)∶YAG作为可饱和吸收体进行被动调Q。连续运转时,在最大有效抽运功率为5.47 W时,获得1.808 W的输出,光-光转换效率为33.05%,斜率效率为36.5%。调Q模式下得到最窄脉宽为7.5 ns、单脉冲能量为87.1 muJ、峰值功率为11.6 kW的输出。采用掠入射式双程放大模块,对脉冲抽运下得到的单脉冲能量为81 muJ、脉宽为13 ns的信号光进行放大,在最大抽运功率下,放大后的单脉冲能量为0.88 mJ,相应的增益为10.86,能量提取效率为19.44%。放大后两个方向的光束质量因子由M_x~2=1.175和M_y~2=1.248变为M_x~2=1.196和M_y~2=1.307。激光器体积紧凑,可采取风冷等措施进行散热,在238 ℃的范围内,输出能量波动小于3%。 |
| 英文摘要 | A compact and wide-temperature Nd∶YAG laser and grazing-incidence amplifier are reported. Fiber-like Nd∶YAG crystal is used as gain medium and a vertical-cavity surface-emitting laser array(VCSEL) is used for the pump source. Cr~(4+)∶YAG is used for passive Q-switch. In continuous-wave (CW) mode, a maximum output power of 1.808 W is achieved at the highest attainable absorbed pumping power of 5.47 W with an optical-optical conversion efficiency of 33.05% and the slope efficiency of 36.5%. In Q-switched mode, pulse with the shortest pulse width of 7.5 ns, single pulse energy of 87.1 muJ and peak power of 11.6 kW is obtained. Grazing incidence and double-passes amplification of laser with single pulse energy of 81 muJ and pulse width of 13 ns obtained by pulse-pump is investigated. With the maximum pumping power, the pulse energy of 0.88 mJ is obtained with the gain of 10.86 and the energy extraction efficiency of 19.44%. After amplification, beam quality turns into M_x~2=1.196 and M_y~2=1.307 from M_x~2=1.175 and M_y~2=1.248. This laser system is compact and air-cooled. The fluctuation of output energy is below 3% when the temperature ranges from 15℃ to 31℃. |
