Am I the only one who is getting really tired of all the spam on this site recently? Is nobody at the helm? Just curious.

While watching a video about a very powerful show laser the author mentioned that the galvo mirror mirror size needed to be increased. And unfortunately increased mirror means bigger galvos and slower. This all makes sense to me. Then I started thinking, would it not be possible to build a...

Here's a link to a great video regarding a 1064 nm 15KW peak power engraver offered by TwoTrees, among others who appear to be selling the same module branded with their own names. https://www.youtube.com/watch?v=UpuN0dS23Nw&t=229s Here's a photo of what is inside. 808 nm pump diode reported...

Sheesh, we need a spam catcher forum page that's before Hologeekery in the lineup. These bots seem to hit the first forum page and yeet. It's to the point where I ignore any new posts in the Hologeekery page because I know they're spam. What a small and niche forum to hit for spam. Target LPF...

Hello All, I'm an IT Nerd that dabbles in electronics as a hobby, so please pardon the potentially 'stoopid' question! I'm working on a project that requires the use of a low-power ~650nM laser in the 5-10mW range, and I've hit a surprising wall in the quest to source a discrete component...

I have a Spectra Physics 120S Stabilite laser acquired in 2016 from a university physics laboratory. This has a wavelength of 632.8nm and was 6mW when it was made in 1966, likely much less now. I have kept it for some time but now need to make room.The head does lase but is erratic and can shut off...
