HELP! ok i'm trying to make a burning laser out of a recycled computer for school, i removed the diode from a dvd burner, and tried just hooking it up to a battery pack but it didn't work, and then i tried connecting the diode to the powersupply but still no laser came up!, I even tried turning on a camera just incase it was infrared, but still nothing =(, really discouraged!, is it even possible and what am i missing?!!!!!

A driver.
You probably fried the diode with the battery
Peace,

Check your school's rules. A lot of places, laser pointers aren't allowed in the building with students. A burning laser is a different story.
It'd be bad if you got in trouble because of a project you picked for school.

@daguin, thx for your reply, what do you mean by driver?, I'm pretty noob at this, and i tried it with multiple diodes, but still nothing, and I really fried the diode with the battery pack of two double AA's?, really?, then how do i get enough power through the diode with a powersupply without frying it...sigh i failed =.=...
@Trevor, thx for your reply and yupp it's all right, i was orinally just planning to do a video and show it that way but he told me to bring it in, surprised me too! #.#, but now it doesnt even work =.=....

The laser diode you used was probably made for reading and not writing. Reader diodes only require a handful of milliamps (<50).
When you hooked up 3V to it, far more current than a handful of milliamps flowed through it; a laser diode is not a very resistive load.
Laser diodes have to be driven by a source that delivers constant current, not voltage.

I'm reall inexperienced at this and thanks for explaining and I think i get it, so if i hooked up a power supply with resistors at the end then attatch it to the diode, would a laser come out,? assuming i have a writing diode, thx for your patience =)

Well... what you want is a current regulated source.
Check out this page:

Use this as a guide:

Also, check out the INDEX link in my signature, lots of good threads in there....

Some of the older lasers from older computers need more power. Did you try plugging it into the wall?

I smell troll too.
If you cant figure it out by the advice given, then GTFO. You're wasting space.

I know what "SMD" stands for and I'm pretty sure you calling us "not nice" makes you a hypocrite.
