We report for the first time to our knowledge an experimental demonstration of wavelength self-tuning in a K5Nd(MoO4)4 broadband-emitting laser crystal (KNM), as well as a theoretical treatment of the system based on its birefringence properties. The self-frequency-tuning of the laser along the full spectral range of the KNM crystal was obtained by rotating a birefringent gain plate in its own plane. The gain plate was placed inside a resonator at Brewster's angle. The tuning characteristics of the spectral filter were obtained by use of the Jones vector formalism. The calculated wavelength-selective tuning precisely matches the experimental observations.
据我们所知，我们首次报道了在K5Nd(MoO4)4宽带发射激光晶体（KNM）中波长自调谐的实验演示，以及基于其双折射特性对该系统的理论处理。通过在其自身平面内旋转双折射增益板，实现了激光器在KNM晶体整个光谱范围内的自频率调谐。增益板以布儒斯特角放置在谐振腔内。利用琼斯矢量形式获得了光谱滤波器的调谐特性。计算得到的波长选择性调谐与实验观测结果精确匹配。
