我也在做PDH方面的工作，不过国内好像还没见报道。

国外这方面已经很成熟了。

Nothing is easy for PHD technique. It involves a lot of electronic design and accurate optical align system. It would be a big project that takes a few years to finish it.

不会吧，需要这么多年才能完成他，这个只是我的毕业设计的一部分，怪不到当时老师给我说这个题目比较新

It depends on what kind of external cavity you are going to use. For a cavity with F 10,000, it will be really difficult. If you use F = 100, then PDH is not so meaningful any more.

A good suggestion is: if it is really your thesis work, then give it up immidiately and change the plan. 99% you will fail in the thesis if you take this project with high finesse cavity.

Diode pumped Nd:YAG laser would be relatively easy to lock, anyway.

谢谢给我这个建议，我再看看吧，毕竟只是论文的一部分，我再问问老师。

If youteacher said it was a big project ,you will lose faith.In fact , you teacher only let you do some pr-research .

其实是经过纵模分裂后得到双频激光频差的稳定，我想首先单频时必须稳定，经过分裂后双频才有可能稳定

用Pound-Drever-Hall's 方法稳定在mHz的数量级可以实现，但非常困难
