摘　　要：在室温条件下,采用脉冲激光二极管侧面泵浦原子数分数为10掺杂浓度的Er∶YAP晶体,实现了工作波长为2712nm的中红外固体激光器成功激射,并得到最大静态平均输出功率1012W,光束质量56,对应光-光转换效率55,斜效率64。这也是目前已报道的唯一实现平均功率10W量级的Er∶YAP激光器。此外,利用声光调Q技术,还实现了脉冲重复频率500 Hz,脉冲宽度63ns,单脉冲能量为58mJ的脉冲激光输出,为推动国内中红外波段激光应用提供了强有力的技术支撑。In this paper,a mid infrared laser with an operating wavelength of 2712 nm is successfully excited at room temperature using a pulsed laser diode to side pump Er∶YAP crystals with a doping concentration of 10%atomic number.In the free running state,the maximum average output power is 10.12W,the beam quality is 5.6,the optical to optical conversion efficiency is 5.5%,and the slope efficiency is 6.4%.This is the only reported Er∶YAP laser to have achieved an average power in the 10 W range.In addition,using the acousto optic Q switching technology,a pulsed laser output with a repetition frequency of 500 Hz,a pulse width of 63 ns and single pulse energy of 5.8 mJ is achieved,providing strong technical support for the promotion of laser applications in the mid infrared band in China.
