稳定大功率单频输出He-Ne激光器的新进展

New advance of high power single frequency He-Ne lasers

继文献[1～3]之后,为了提高输出功率,并消除放电毛细管不规则带来的腔损耗,作者研磨了放电毛细管的内壁,将输出功率进一步提高到24mW。此时激光器的主要结构参数为:腔长1140mm,放电管长1m,放电管内径2.48mm;采用平凹腔结构,凹面曲率半径为4m,

26mW stable single frequency output was obtained from an extracavity He -Ne laser of 1m long high gas pressure longitudinally discharge tube with additional unhomogenieous magnetic field. Conversion coeffieient from multi-frequency into single frequency output is greater than 1. This type of laser has a p.d value of approximate constant, being 10-13.
