有哪位高手在做OPO啊？？

想请教一下现在的OPO都有用那些腔型？？
泵浦光是怎么偶合到OPO的晶体中去的呀 ？？

我的QQ12510605。。。

泵浦光直接入射到有OPO晶体的OPO腔中，就可以了。

要看你的OPO腔片类型。从全反镜处泵浦当然好，不然就使用45度反射镜将泵浦光引入，此时该45度镜应该是对泵浦光45度全反，对OPO的调谐范围高透。

<P>那为什么要用45度全反呢？插入了45度镜片不是增加损耗吗？加入了45度有什么更大的好处？</P>

<P>下面的光路图，是采用好的腔片才行。全反要求宽带全反/泵浦光高透（增透）</P>

<P>加入了45度镜片不是增加了腔内的损耗了吗？这样不是很亏？</P>

qggq222 发表于 2004-4-24 00:01:00

<P>不是这个问题。你得考虑膜片能不能镀。至少在国内大宽带全反，532nm增透的膜片还镀不好。</P><P>上次我单位有人花将近2万RMB买来进口腔片一对，就可以覆盖整个调谐波段。好是好，就是价格.......</P>
