摘要

建立了一种高质量、高效率全固态中红外激光系统，并对激光输出的效率、光束质量等指标进行了测试。首先，以二极管激光器为泵浦源，Tm3+∶YAP晶体为增益介质，搭建了输出波长为197 μm的近红外激光器。然后，以Tm3+∶YAP激光器为泵浦源，自行开发研制的Cr2+∶ZnSe单晶为增益介质，搭建了全固态中红外激光器。最后，测试了全固态中红外激光器的光束质量及激光器出光效率，并对谐振腔光效率的理论输出值与实际的激光器出光参数进行了对比。实验结果表明: 此全固态中红外激光器的光光转换效率为172%，斜率效率为20%，在最高输出能量为3 W时的光束质量(M2)在x和y方向分别为17和173，光束基本为圆形的高斯光斑。

Abstract

A kind of all solid state Mid-IR laser system with high quality and high efficiency is built. Firstly, we use diode laser as the pump source, Tm3+∶ YAP crystal as the gain medium, to build a NIR laser with the wavelength of 197 μm. Secondly, we use NIR laser as the pump source, a self-made Cr2+∶ZnSe single crystal as the gain medium, to build an all solid state Mid-IR laser. Finally, we test the quality and efficiency of output laser, and comparison of the theoretical output efficiency of the laser with the actual parameters is carried out. The experimental results show that light-light conversion efficiency of the all solid state Mid-IR laser is 172%; slope efficiency is 20%; the beam quality(M2) of the highest output at 3 W are respectively 17 and 173 in x and y direction; the Gaussian beam is circular.
