No matrixcs, his wording was correct, his reference to a spectrometer confirms that. IR diodes come in many different wavelengths ("colors", if you will), although they are all outside of the regular range of human vision.
I also think I know why he may be asking, as certain IR wavelengths have
particular usefulness where lasers are concerned!
alx, the diode you are referencing in the PHR-803T is actually a
combination IR & red laser diode. The IR laser is used for CD's, and the red is used for non-HD DVD's. It's pin-out (large pic) can be found in the extensive thread here -

I've also attached a copy of the pic for you below. (A Google Image search also turned-up a smaller drawing that can be found at the LSP site, but I don't dare copy/post that here!

But to answer your question, the wavelength on the IR portion of this device is
not a 808nm (so unfortunately it
cannot be used to pump a YAG or vandate solid-state laser, nor the crystals for a DIY green laser). :cryyy: It is a 780nm, just like for CD drives.
As to the power, that would depend on if it was being used as a burner or not. If it was just a reader, then it would likely be <= 5mw, if it was designed to burn, then it would likely be higher. Ditto for the red/DVD portion.
The drive the PHR-803T came out of, however, was early models of the Toshiba SD-S802A HD DVD
ROM Drive, used inside the XBOX 360 HD-DVD
Player, so I wouldn't get my hopes up about high IR power!
In fact, you would probably be better-off pulling the IR diode from an old 52X CDRW drive.
