it wouldn't be as powerful, though it would probably still work.

No it wouldn't.. It wouldn't work for anything, other than damaging your iris, a bit at a time. Those are IR, and really low power at that! Not usefull!

Theyre not all infrared. The one from my cd player is visible. Besides, infrared lasers can burn through things too. And like I said it would still do a bit, just much slower, and much thinner things.

How the the hell would you cut something with a diode with a MAX output of 5 mW? What your saying is "hey i'll use this cool red laser i just got bought in the dollar store to cut black tape!" omg..

First of all...calm down. Who said anything about the dollar store? Dollar store lasers are 1mw. A laser used to read cds is more powerful.

Fine, i'm sorry i'm not from the states, so i have never seen the lasers in the dollar store.. Regular red laser pointers are 5mW. Cd lasers have 5mW MAX output, you can not cut anything with them.

fyi, i just tried a cd laser out, straight from the player. I held a battery to the leads, and put it near a plastic bag...smoked instantly.

It was the whole aparatus, so I'd assume there was already a lens.

iR is REALLY POWERFUL it's also cheaper to maufacture it's really dangerous, if it accidently got shone in your eye you could be blind. With IR you have no blink reflexes.

Actually red light is on the weaker end of the spectrum. If you want high power, go for blue or violet. Those have the most energy. IR is only dangerous because you can't see it.

I recommend to buy a DVD burner for cheap and use that laser

I just got the diode out and hooked it up to 2 AA batteries at first it was nice and bright but i dont know if i shorted it or something because now it is weaker than my cheepo $1.50 laser pointer. I had a short glimpse of its potential!! What happened did I ruin it?

Most likely yes if you don't have a driver for it it will burn out the diode I did it to mine on accedent so now it will never be as strong as it was before sorry

no u put toooooo much power into the diode at 1 time......with a module there is a steady flow

ya thats a good possibility because i never shorted the diode to prevent static damage. I guess I learned my lesson! thanx for the info

Is anyone making one? I am! Only thing I need is a freaking colliminating lens, and I'm not going to shell out money.. I'm testing alot of wierd lenses, I've got laying around, but no luck yet.. Any suggestions?

you can use the dvd writer lens themselves, but have a good luck focusing one (it can be done, but is a bit hard)

Best I've Googles was this:

colliminating lens

See the little picture, and then get some lenses like that, out of the ones you have.

What is shorting the diode? Could a magnifying glass make it more intense? If you make a sliding grid to mount this on, you could trace a line drawn styrofoam/cardboard(maybe) to make the cutter mentioned earlier more effective

Also, would a peep hole work for the lens?

No. You need a colliminating lense, not a peep hole..

A colliminating lens takes all the light, and focus's it into a a small beam of light. A peep hole does the same thing..so why wouldn't it work?

no,  the "peep hole" idea dosent reflect the beam into 1 spot it just blocks out the other light so the light is still dim.......... its not concentrated into 1 spot

You need to short the diode before you use it, or it will most likely be killed by static. No. No.

But I asked what is shorting the diode. Not why.

If it works with the sun, why not a laser?

And the last bit wasn't a question...it would work.

no it most likely wont work. when you magnify the sun like that, your actually just condensing a wide beam. lasers are already a thin, powerful beam so it wouldnt do any good.

Heya! Impact2us
start with the parts... im nooby at instructables so i dont no waht picture............................. but wanted to tell you that you shouldnt use a cd burner cus they are ir burners(infa-red) so u wont be able to see them! and a much more unsafe.I recomend that u go get a dvd burner  from sum garage sale or sumthin or check the computers for a dvd writer -should say on them wether they are or not

After a few failed attempts, i ended up buying a laser from http://www.dragonlasers.com. One of the lower powered ones.

My advice to any one using the diode from a cd drive, be very careful with the input power or you'll fry the diode.
