摘要
设计了一种高能量微片激光光源。其利用808 nm激光器作为泵浦源,采用掺钕钇铝石榴石/掺铬钇铝石榴石(Nd∶YAG/Cr∶YAG)键合晶体作为激光系统的增益介质和被动调制元件,实现1064 nm激光输出。通过设计仿真,确定键合晶体的饱和吸收体初始透过率、谐振腔长度和输出镜反射率参数。将泵浦源、键合晶体等元件进行集成封装组成光学系统,通过实验测试,最终获得了3 ns脉宽、1 kHz重频、208.7μJ能量的脉冲激光输出。
A high-energy microchip laser source was designed.The system employs an 808 nm laser as the pump,utilizing Nd doped yttrium aluminum garnet/Cr doped yttrium aluminum garnet(Nd∶YAG/Cr∶YAG)bonded crystals as gain medium and passive modulation element of the laser system to achieve 1064 nm laser output.Through design simulations,key parameters such as the initial transmittance of the saturable absorber in the bonded crystal,resonator length,and output mirror reflectivity were determined.The pump,bonded crystals,and other components were integrated into a compact optical system via holistic packaging.Experimental testing of this system ultimately achieved pulsed laser output with a pulse width of 3 ns,a repetition rate of 1 kHz,and a high-energy level of 208.7μJ.
