If you're not into electronics then just buy one from DTR. If you have the skills to build a step-down constant current buck driver then you can start searching your buck regulator ic, it's not impossible at all. I like the texasinstruments site, they have a lot of good regulators, and the...

Yes, I know that. My question is about gaussian beam parameters and how can I calculate those values. I want to describe a real life laser with them but if I apply the formulas the results are too extreme to be true. I want to know that why my calculated beam divergence is so small compared to...

I hope it's the right forum for this topic. I'm new to lasers and I'm trying to understand the physics behind, yesterday I read about Gaussian beams. https://www.edmundoptics.com/resources/application-notes/lasers/gaussian-beam-propagation/ I read the first 7 paragraph of above article (and a...
