New experiment for green laser

CurtisOliver said:

Your laser is a DPSS. You have two crystals in there. The first is a Nd:YAG which outputs 1064nm and the second is the KTP doubling crystal. Now Nd:YAG's major absorption line is at 808nm. The same wavelength as the IR diode you have extracted. It doesn't however accept 650nm, so it won't produce no output at all. So the first crystal will not have enough gain to produce the needed 1064nm for the KTP to double in order to output 532nm.

Edit: The reason why it has not been tested yet is because we already understand the process enough to know it won't work.

It probably isn't Nd:YAG actually, most, if not all modern pointers use Nd:YVO4 for 1064nm.

But yeah... won't work. You'd get some red out of the front, but it won't be a nice spot and won't be collimated well at all.




You smell that? Smells like Nd:YVO4 burning!

Do not worry, everybody here is to learn as well. We all were beginners in lasers. The more you learn the more you can enjoy the lasers and use them for/in some projects. At least you have some components to experiment with. But make sure you stay safe.



Exactly.
