how much output is an infrared producing if it glows as bright as a 3mw red laser pointer?
i tried running 320ma at 6 volt through laser inthe pioneer dvd burner drive
 





It's not an easy question to answer because it depends on your sensitivity to 808nm light. Everyone is different. About all that can be said is a general guess but it really requires a meter to know for sure. If it's as bright as a 3mW red it's quite a bit or IR. 808nm, to me, looks dull red and never looks like a bright laser spot.
 
you need a power meter if you want any kind of real answer... sounds like a lot though... you could probably burn matches at a further distance if you could focus it properly...
some people can see further into IR than others... some people can even see the LED's in TV remotes... so it's really hard to say.

you do have goggles, right? that sounds like quite a lot... also, don't IR diodes take like 1.5 or 2v? are you sure there's 6v across the diode, or is that your input voltage?
 
Hmm... from what I have read(I may be wrong), you are probably killing that diode.. diodes take up more voltage as they die. Most IR diodes like yours run happy with about 2v@150mA, MUCH lower than you are running yours. It probably is putting out a nice amount of power.. but not for long.

If I am wrong, I am sure someone will say so:)

His laser is around 780nm, which is about 5 times brighter to us than 808nm. I have a couple 780nm lasers and the 100mW looks like a mW or two, I don't like to play with those anymore because I don't have goggles for that wavelength.
 
It must also be puting out a lot of heat.Probably near 1.5W to dissipate. :-/
