变反射率镜非稳腔Φ20 mm口径Nd:glass激光器研究
A Φ20 mm Nd:glass Laser Using an Unstable Resonator with Gaussian Mirror
摘要
详细分析了高斯变反射率镜非稳腔的腔模和输出特性，给出了各阶横模的解析表达式。采用高质量的高斯变反射率镜在Φ20 mm大口径Nd:galss激光介质上实验研究了这种腔的输出特性，获得了10 J级发散全角为0.18 mrad近衍射极限的高强激光束，该发散角只有相应普通非稳腔的18%，同样泵浦时输出能量约为普通非稳腔的70%。最后实验研究了这种腔结构的失谐灵敏性.
Abstract
The analytic results of TEM modes in an unstable resonator with Gaussian variable reflectivity mirror are given. The output characteristics of a Φ 20 mm Nd: glass laser using a resonator of this kind are studied experimentally. The output beam has a near diffraction-limited divergence of 0.18 mrad and about 10 J energy. Its misalignment stability is studied,too.
