So.... after i moded my dx cr2 laser it worked for about 2 seconds then it died. Now when I look in it i can only see a weak infra red light. What did actually happened? What can i do to fix it?

ahh! stop! dont look into the IR! its 1000 times brighter than that really looks! its like looking into the full powered green laser but you cant see it!

did you pot mod it? you may have turned it too much, try turning it back, if it doesnt work, then yes, you probably over powered it and it wont work now.

again, NEVER look into the IR.
 
I know is dangerous , i looked in it through a digital camera. :) anyway thanks for the advice!
Yes, i did pot mod it and i have tried to mod it back but nothing happened. :( If it still emits IR it means that the diode is not totally broken right? So what can i do to repair it? :-/
 
i dont think that you can repair it, you will just need to get another one, (of course you could send it to me so that i could use the barrel ;)) but you have broken it beyond repair :'( you should have looked around to see how pot modding usually doesnt work, and ya, good thing you looked into it with a camera instead of your eye! 8-)
 
I can't understand why it still emits IR if the diode is broken.:/

It is kinda like when you fry a red diode, even though it's dead, it still emits a little bit of red.

ya, you also could have fried the crystals :o

so this means that the IR diode is still working? if so how can i focus it to make a ir burner? now i can't feel any heat on my finger.
 
i have a moded ir laser it was green ,bought it from dx,the 50 mw version when i put my finger infront of the laser i cant feel heat but if i put there a match instead of my finger it lights it up , try pointing it to something black and dont foget to use googles !
 
If the diode is okay but the crystals are shot, you could try making it into an IR. I guess you could verify this by shining in onto a piece of paper and looking at it with a digicam - should be well visible if the diode is okay. You might need to get the crystal set out of the way first though as that could be in the way.

Also, you have to adjust and possible replace the focussing optics as they are set for the crystal, not de diode output. Kinda tricky work when you are working with almost invisible light.

that could be bc ir is absorbed differently than visible light, i think
 
i have one of these. When it came it was mode hopping. I turned the pot to the right (down) and it stopped. I figured id try to turn it up and try and get a beam like this guy on youtube http://www.youtube.com/watch?v=NZZUQdnBahg&feature=related
...Problem is this guy doesnt want to spill the beans on the way he mods it!  when i turned the pot up (to the left) the dot got alot brighter, i could see the beam very well.... untill it started mode hopping again a few seconds later. It turned in to three beams. so i turned it back. still works. its a good little laser.

Yeah, that's the "fill your room up with smoke" mod, it's top secret, don't tell anyone!

Yep, all he did was put just enough fog in the room that the camera couldn't see it, but enough to make the beam really bright. You don't need much fog at all to see a laser beam. Notice that the dot isn't as bright as it should be for a beam that bright.
