这两种匹配究竟有什么区别?
还有有些晶体只有一类或二类匹配又是怎么回事?
请各位指点一二,多谢哈!
各位兄弟姐妹阿
大家帮帮忙阿,谢拉!
我也想学习学习,
请高手们来指点指点!
帮顶
Two types of phase-matching are classified in consideration of polarization of lasers. If the polarizations of two input beams (for sum frequency) are parallel to each other, it is called type I phase-matching. If the polarizations are perpendicular to each other, it is called type II phase-matching
找本非线性光学看看就知道了
以前学过的,不过现在忘记的差不多了
楼上说得对,这问题不是一两句话就说清楚的,最好找本非线性光学或者晶体光学方面的教科书来看。
在和频并且是负单轴晶体情况下:
I 类匹配:wave1(o)+wave2(o)=wave3(e)
II 类匹配:wave1(e)+wave2(o)=wave3(e)
wave1(o)+wave2(e)=wave3(e)
当然还有其他不同情况,可以参阅相关的参考书
