【摘要】：报道了一种基于内循环水冷系统的10 MW级高峰值功率窄脉宽小型化电光调Q Nd∶YAG激光器。采用机电一体内循环水冷结构,有效地减小了激光器体积,整机尺寸为320 mm×150 mm×150 mm。当LD泵浦源能量为800 m J时(注入电流为100 A),获得了137 m J的静态激光输出,光-光转换效率为17.1%;电光调Q后在驱动频率为30 Hz的条件下,获得了100 m J,脉宽9.9 ns的激光输出,光-光转换效率为12.5%,动静比为73%。激光器连续工作1.5 h不稳定度小于3%。
[Abstract]:A 10MW high peak power narrow pulse width miniaturized electro-optic Q-switched Nd:YAG laser based on internal circulating water cooling system is reported. The volume of the laser is reduced effectively by adopting the internal circulating water cooling structure of electromechanical system. The size of the whole machine is 320 mm 脳 150 mm. When the energy of LD pump source is 800mJ (injection current is 100 A), the static laser output is 137mJ, and the optical-optical conversion efficiency is 17.1.The laser output of 100mJ and pulse width of 9.9 ns is obtained at the driving frequency of 30Hz after electro-optic Q-switching. The conversion efficiency of light to light is 12.5 and the ratio of static to static is 73. The instability of the laser is less than 3 in 1.5 h.
