class="postmsg">怎么全是英文啊？发点中文好吗。</div> <div class="postmsg">谢谢上面诸位的回答。ujinlog同学给了一些资料，但是回答的是线偏光经过二分之一以及四分之一波片后的情况，而没有针对光纤输出光的情况来具体说明。线偏光经过光纤后变成部分偏振光还是圆片光？<br /> <br /> 85667542同学回答的部分偏振光经过四分之一波片后变成了线偏光，这个能给个解释吗？这样转换后又能量损耗吗？比如太阳光（随机偏振）经过起偏器后，理论上就有一半的能量损耗。</div> <div class="postmsg">大学物理虽然学过这些东西，但是都忘了。谢谢ujinlog</div> <div class="postmsg">感谢分享 不过还是不完全了解 经常在光电系统中见到这样的组合 一片半波片之后组合四分之一波片 可是我并不了解这么做的用处</div> <div class="postmsg">一直都搞不清楚的东西，正好仔细学习下，感谢ujinlog提供的资料，稍后总结心得与大家讨论，</div> <div class="postmsg">四分一波片quarter-wave retrader用于线偏振光与圆偏振光之间的转化，条件是线偏振光与四分之一波片的快轴成45°角的时候，如果不是45°，线偏振光的能量不能平均分布到四分之一波片的两个轴上，那就可能是椭圆偏振光了。<br /> 四分之一波片通常可以和一个偏振片构成光隔离器，用于消除不需要的反射光线，激光器中从腔内射出的光线，如果不想再让其回到腔内，就可以使用这种方法。<br /> 二分之一波片又被称为偏振旋光片polarization rotators的作用是将入射的线偏振光偏转一定的角度，该角度是入射线偏振光与二分之一波片快轴夹角的两倍，（慢轴上的光线没有被矢量分解，这一点与四分之一波片不同，待证实）当夹角是45°时，入射的线偏振光会被转动90°，当入射光线不是线偏振光时，可以将左旋偏振光转化为右旋偏振光，在实际中用于改变激光器的原始偏振方向。</div> <div class="postmsg">全波片用于消除线偏振光的畸变，例如当激光系统输出的线偏振光在经过某金属反射面后变成椭圆偏振光，可以通过微调全玻片的快轴或慢轴来精确的消除偏振畸变。<br /> 以上资料来自ujinlog的附件，meadowlark公司的产品说明册，都是在补以前漏却的知识，呵呵，有不对的地方，大家指正，共同学习啊。</div> <div class="postmsg">这个必须顶，四分之一波片的快轴或慢轴与线偏振光成45度时才能转化为圆偏振，这我是知道的，但是半波片和全波片，看了大家的讨论，学习了</div> <div style="height200px;"></div> <ul class="xl xl2 cl" style="border-top: 1px #cccccc dashed;margin:5px 0
