【摘要】 <正>在激光光谱、调制等研究领域内,常常要采用线偏振的激光器,有时还要求光场偏振方向同外加电场或磁场方向成某种角度（例如乎行或垂直）,这就需要测定激光器输出激光的偏振取向及偏振度.在可见光波段,通常采用旋转尼科尔棱镜的方法,而在红外波段,便没有类似的棱镜可采用.本文介绍一种简便方法,使被测的CO₂激光通过一个可绕光轴旋转的布鲁斯特窗,测定布氏窗在不同转角下的激光反射及透射强度,即可确定CO₂激光的偏振面及偏振度.这种方法也适用于其他波段的激光器.更多还原

【Abstract】 A simple and useful method for determining polarized performance of CO2 laser is described.
