<b>啥是偏振烧孔:</b><div class="postmsg">各位大侠 有谁给咱解释一下啥事偏振烧孔<br /> 我对光纤这方面不太懂<br /> 谢谢</div> <div class="postmsg">哈哈，老头！<br /> 没人理你啊~~~~~~~~~~~~</div> <div class="postmsg">呵呵，既然高手不乐意回答，我来说一下。<br /> 所谓烧孔，即是某种状态占用了多数资源从而限制了其他状态的产生。<br /> 激光中的偏振烧孔就是一种偏振状态因为占用了多数的受激辐射光放大的光子，抑制了其他谐振条件应该产生的偏振激光。<br /> 激光中的烧孔效应还有，模式烧孔等。</div> <div class="postmsg">不管你说的 我是不是完全明白 我先谢谢你</div> <div class="postmsg">这么说的话 就是偏振烧孔可以利用 用来产生偏振光？</div> <div class="postmsg">应该是可以的吧！<br /> 高手说看～！＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝</div> <div class="postmsg">合力合兴光电全体员工帮你把帖子顶起来！</div> <div class="postmsg">顶~~~~~~~~~~~~~~~~~~~~~~~~~~~~·</div> <div class="postmsg">激光是由于受激辐射和光腔的选模作用实现的，它的单色性好，相干性好，方向性好，亮度高。激光器通常工作于多模振荡，表现为空间上产生多模横振荡，纵向上具有多个频率组分的振荡。介质的增益饱和效应有均匀加宽的增益饱和效应与非均匀加宽的增益饱和效应，它们影响激光器的输出激光。均匀加宽稳定激光器应为单纵模输出，但激光较强时，会出现多纵模振荡。激光越强，振荡模式就会越多。当频率为 的纵模在谐振腔内产生稳定振荡时，腔内就会形成驻波场，波腹处的光强最大，波节处的光强最小。频率为 的模在腔内的平均增益系数为 ，但轴向上各点的反转集居数密度和增益系数不同，波腹处增益系数最小，波节处增益系数最大，这一现象为增益的空间烧孔效应。</div> <div class="postmsg">昨天给你查了一下手边的书，还是没有结果。<br /> 你查过《导波光 学》么？</div> <div
