现在制造黄色激光的关键是如何产生：1,342nm 的激光。据有关资料是采用NdYV04泵出来1,342nm 的激光，然后通过KTP倍频。难题就是窄带镀膜！！！！

这里有一篇文章是国外讲如何产生黄色激光的。黄色激光可是胆固醇分子的吸收波长，对分解胆固醇有很大的意义！！！！ ：：593.5nm yellow DPSS laser (pointer or larger size), there's a BIG infrared laser diode that generates laser light at 808nm, this is fired into a crystal containing the rare-earth element "neodymium". This crystal takes the 808nm infrared laser light and lases at 1,064 and 1,342nm (yes, deeper in the infrared!). This laser light comes out of the NdYV04 (neodymium yttrium vanadium oxide) crystal and is then shot into a second crystal (containing potassium, titanium, phosphorus, usually called KTP) that roughly doubles the frequency to 593.5nm - the bright orangish yellow color you see. This light is then collimated (focused) by a lens and emerges out the laser's "business end". Just before the lens, there's a filter that removes any stray IR (infrared) rays from the pump diode and the neodymium crystal

是和频，不是倍频

我觉得现在的光学镀膜应用在激光上的做的还是可以的，

窄带膜的要求是什么，

不会做不了吧？

拉曼效应可以出来黄光吗？
