Make a laser from a cd player?

Can it be done? I mean something has to read the disc.

CD players do use a laser diode -- but usually not in visible wavelengths, so it isn't much fun to play with. DVD players use a laser which is much more entertaining (and more powerful); see many posts here on Instructables for details.

but can it still be done
Sure. Remove the laser diode, mount it in a heat sink, hook it to an appropriate power supply. It won't do anything very interesting except emit a bright beam of infrared light, but it will be a laser.

That's hard, but if you know how a CD player laser works, you can make it.
