I did read the Wikipedia article, but it hasn't changed much in over 10 years. The last time someone added new information was in 2010, and that got removed as copyright violation.
However, this sounds very promising:
Does this mean we can expect future laser diodes to have really high...
I did find some websites claiming to have them for sale:
I recently became aware there is a new class of solid-state lasers based on quantum dots. From what I gather, they're supposed to have really good specs. However, there doesn't seem to be much information about them. So my questions are:
1. How energy-efficient are quantum dot lasers compared...
A long time ago, everyone said that all 405 nm lasers are single-mode. It seems this no longer the case. Considering that single-mode operation is required for optical disc drives, these diodes are likely intended for projectors and such.
Posted this in Discord but thought I'd share it here too. One idea to reduce spam would be to add an additional CAPTCHA on the sign-up page. For example, there could be a question like, "What does LASER stand for?"
A side benefit is that this would require the user to do at least some basic...
Has anyone here used one of those lasers?
We have a few of these lasers at work in our hardware labs. I couldn't find much information about these lasers, but they seem to be identical to the SDLaser 301 or 303 models. Although we don't have any balloons, matches or anything to test their...
