Just FYI, none of the pictures seem to work anymore, in this thread or the "original" thread, and the o-like website doesn't seem to be online anymore either

I wouldn't look into removing diodes from DPSS lasers. The IR pump diode is actually 808 nm. The Nd:YAG or Nd:YVO4 first lowers the frequency, or "stretches" the wavelength to 1064 nm, before entering the KTP (potassium titanyl phosphate) crystal which does the frequency-doubling, or...

This is very true. It took me a minute to realize that shorter on-times means less photons emitted, which means less average power and less brightness. But it still seems like it would be a nice utility to have adjustable laser power. It would be awesome to have a full-sized potentiometer with a...

I have noticed most laser pointers are being powered with 100% duty cycle (always on) power supplies ( at least most constant current laser drivers that I've seen so far in my research). What is the reasoning for why lasers are not powered with PWM (at a high frequency so you don't see any...

Okay. Thank you everyone! I guess I will need to spend some money then... Damn!

Survival Laser hosts are moderately priced (but still too expensive in my view). I am, however going to purchase my eye-protection from them! I think you're using the word "cheaper" where you should be using "easier" or "more convenient". It would be too easy to instantly satisfy my...

UPDATE Sorry for not looking at other posts in this subforum first... my bad... There was a very recent post where "whytho" asked a similar question... but he had already bought a module he wanted to use, and THEN asked. This why I ask questions BEFORE buying anything! ;) So, I guess I can...

Hi y'all I am considering buying a cheap green or red laser just for the host (the kind that uses an 18650, like 301/303 or "assassin"), then removing the diode or module and fitting a different one in there. But... Do you think it could work? Every time I search for hosts, they are all a...
