    摘要:

    报道了一种多波长LD泵浦方棒状Nd∶YAG无温控固体激光器。激光器采用LD侧面泵浦方式,LD泵浦模块由四种不同中心波长的LD组合而成,常温25 ℃时,各bar条中心波长分别为802 nm、804 nm、806 nm、808 nm,LD模块光谱半高全宽为7 nm左右;工作介质为侧面双通方棒状Nd∶YAG键合晶体,通过控制光路可以增加工作介质的有效吸收长度;调Q方式为电光调Q;得到一种无温控固体激光器。该激光器在-40~+60 ℃温度范围内,可以无温控稳定输出能量≥40 mJ;输出激光水平方向发散角θ2x=1.79 mrad,垂直方向发散角θ2y=1.36 mrad;光束质量:M2x=4.858,M2y=2.697。

    Abstract:

    A multi-wavelength LD pumped square rod-shaped Nd∶YAG temperature-free solid-state laser is reported in this paper.The laser adopts LD side pumping mode,and the LD pumping module is composed of four LDs with different center wavelengths.At 25 ℃,the center wavelength of each bar is 802nm,804nm,806nm,808nm,and the full width at half maximum of the LD module is about 7 nm.The working medium is a side double-sided square rod-shaped Nd∶YAG bonded crystal,and the effective absorption length of the working medium can be increased by controlling the optical path;the Q-switching mode is electro-optic Q-switching;and a temperature-free solid-state laser is obtained.The laser can be temperature-free and stable output energy≥40 mJ in the temperature range of -40~+60℃.The horizontal divergence angle of the output laser is 1.79 mrad,and the vertical divergence angle is 1.36 mrad,the beam quality:M2x=4.858,M2y=2.697.
