现有一激光二极管泵浦nd:yag激光器,其功率和频率都不稳定,现要设计一接收反馈控制电路,谁有经验请赐教
频率不稳??使脉冲的??
功率不稳是由两方面的因素造成的:1,泵浦源的稳定度;2,热稳腔的设计,如果你找了造成不稳的本质原因,就可以解决了。
不是脉冲的,是连续的
这是激光器的稳频问题。
主要与谐振腔的腔长和介质的折射率有关,对二极管泵浦nd:yag激光器的稳频比较困难。
你可以看看激光技术方面的资料

端泵,功率大概有170多毫瓦,时间长了可能就降到160或150多了

I have been working on active laser stabilization for 3 years. For the Nd:YAG laser, stabilization is quite sample. One can easily reach mHz level.
Don't believe? Read something about Pound-Drever-Hall's laser stabilization techniques. This is the best technique available to date.
This stablization tech is interested for me。 Can u introduce it to me?
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。
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.

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
