The results of an experimental investigation of the performance characteristics of a Q-switched Nd:YAG laser utilizing a negative-branch unstable resonator is presented. Measurements indicate that near diffraction-limited beam quality has been attained with a system in the rangefinder/designator energy category. In a performance comparison with a conventional parallel-plane mirror resonator, the unstable resonator was found to produce equally efficient operation with greatly superior beam radiance and tolerance to mirror misalignment.
本文给出了利用负支非稳腔的调Q Nd:YAG激光器性能特性的实验研究结果。测量结果表明，在测距仪/指示器能量范畴内的一个系统已实现了接近衍射极限的光束质量。在与传统平行平面镜腔的性能比较中，发现非稳腔能产生同样高效的运转，且光束辐射度和对镜面失调的容限要优越得多。
