What about Lightscribe Diodes?

[meatballofall]

HP's Lightscribe Disc Burners... they can etch images on the surface of Lightscribe Discs at high speed. I've been looking for something about them on this site for awhile and haven't found anything... The drives are pretty cheap and I bet the sleds for them are even cheaper...

Is there anything special about the diode inside these burners? Does anyone know the wavelength and power output? Or have they already been found to be nothing special and I'm just way out of the loop?

When it comes to etching, the prefered wavelenght is infrared, wich gives out more heat. Unless you want to make a green laser or a blue one or burn stuff, these are pretty useless because you can't see the beam... And infrared is very dangerous to the unprotected eye, better wear safty googles ...

There were a few threads about these.They're nothing special.The drive just uses the usual diode for CD or DVD (can't remember) burning for the lightscribe process.They basicly have the same diodes inside. :-/

few corrections .

IR diodes don't give out more heat . a 1W IR diode and a 1W red diode both give off the same "heat" when the light is absorbed by something, granted they have the same absorption rates .

IR diodes are used for etching because they are cheap and can reach higher powers than most other diodes.

Infrared is just as dangerous as any other laser, and the same precautions should be taken when handling any laser over 5mW .

Ah I see I see, so to invest in one is a definite WASTE... thanks for info guys! Infrareds are cool... but not what I'm looking for...

Cant use the infrared diode from a cd player/burner. It's ~790nm (or 780... one of the two... either way the next statement is still true) which is pretty much useless for pumping the common solid state lasing mediums.

808nm is king

Well, I'm also learning new stuff...!
