Misalignment loss of rectangular waveguide CO2 laser with grating
-
摘要: 稳频调谐矩形波导CO2激光器中采用光栅选支,要求光栅具有精确的安装角度,以避免损耗过大或出现跳支现象。研究了安装角的偏差带来的损耗与偏差角之间的关系。介绍了一种基于三角法并使用铅垂线校准光栅安装角度的方法。计算表明,用该方法安装光栅具有较高的精确度,其安装误差角造成的损耗非常小,而且振荡支线稳定。Abstract: The misalignment loss of the grating in the wave guide CO2 laser is studied in this paper. And a experiment method for grating obliquity adjusting is also discussed with its accuracy.
