UV Lasers

[Relo H]

I was looking online for a UV laser. To be clear this laser needs to be less than 400nm. I was looking for something upward of 3watts. I havent been able to find anything. Do you have any links that I could use to buy one. The more powerful the better.

You're going to be well under 1 watt with anything lower than 405nm.

This is one of the best, if not the best, of your options available.

lol the price

Sub 400nm at 3+ watts? Nitrogen/TEA laser is the only thing that comes to mind that doesn't cost as much as a decent car. Nitrogen lasers are pulsed though, if you need true CW then best of luck to you.

Nope. Not getting 3W at <400nm for anything affordable any time soon.
I do have a cheaper alternative but still not cheap by any means. UV laser marking systems use a 355nm DPSS 3HG source.

Quite the bargain @ only $3200 for the 5 watt unit. But again, these are pulsed instead of CW.

True but they are 20-150kHz so we wouldn’t perceive them as pulsed at all.

Thanks for the help. I was looking for something that is off the visable spectrum( In the UV direction). Too bad they cost so much

 

[WizardG]

IR is cheap.

They don't. That's actually quite cheap for laser system. Only terrible beam quality diode lasers are cheaper (when available)

If you're just looking for a non-visible laser and it doesnt have to be UV, IR is the way to go. Plenty of cheap and decent options for IR since they get used as pump sources for DPSS lasers.
