Looking for a laser that can burn white paper at 10 feet

My 500mW 405 reliably burned 1 to 2mm holes in a sheet of white paper at ~11 feet when focused to infinity. So, I guess you'd want something like that.
 





For burning at 10' a single mode laser will almost certainly be better than most 445s. A really good 405 should be just the ticket. You can do it with a beast of a 445 (think 9mm diode) but the beam specs on those multimode diodes are relatively poor so much more power will be needed making CR123 batteries impractical.
 
Short answer: doesn't exist. I'd start setting lower expectations.

Remember that the visible lasers that you see on this forum are really considered low-powered lasers. Even those 2W 445nm lasers are pretty low powered as far as burning is concerned.

I think I Frothy Chimp show off a Q-switched Nd:YAG green laser that could probably do what you asked, but it's way out of your price range, is not portable, and certainly wouldn't use primes.
 
Well, pinholes in white paper at 10 feet as mentioned above is what I'm looking for, albeit, it appears that model (If the one I found was the same model) does not use the 123 primary batteries I'd prefer.
 
I've got Blord making me a 500mW 405nm laser right now. sounds like it could be quite the burner. I believe it uses 16340 batteries, and cr123 could likely power it too, but 16304 are 3.7 volts and cr123 are 3 volts, so it wouldn't be full power on the cr123s

Sorry BB but I have one here right now and I just took pictures of it doing just that, burning a hole through
off white printed on printer paper at 10 feet measured :D










And the end result @10 feet measured.


You can see the paper is not pure white as it had some printing on it which made it easier to heat.

Hey pyro, we're talking pure white here, but I am curious how many watts of 445 you have there. looks like at least 2. I tried this experiment the other night, as I just got my new lenses from rayfoss, and my rifle fails on pure white, at ten feet, focused to infinity. granted these are the three layer lenses on 1.5 watt, I am guessing you have a g2 on there pyro?
