Hello!
We do have a cost effective solution too: https://www.live-lasersystems.at/d/laser-modules.html

Hey guys,

a lot of stuff has happened since the last time I posted! I went to the US for a semester abroad and started doing my master's at a laser place - My colleagues there were so incredibly kind to lend me a place for my experiments and a small Verdi laser.

So, finally I got it to lase, first with the Verdi Laser and after it was optimized at that working point, I got it above threshold with one of my 461nm FAC diodes. It is barely above threshold and only with a near HR mirror (prob 0.1% T) so there's a lot to do still. But: It is done, it lases only with a blue diode!

Here's two videos showing the results:

An infrared viewer makes the spot much more visible than my smartphone:

I cant use all the diodes since they are not perfectly aligned. But I will probably redesign the entire thing anyways. Those >3 W blue diodes are just a nightmare M²-wise.

congrats. I got nowhere.
