Recently the family laptop broke and I've been allowed to open it up and take a look inside to educate myself as I am hoping to take a computing course soon and an IT engineering course. But while searching I found the DVD drive with a sticker stating that it housed a Class 3B laser both visible and invisible (I assume that's an infra-red). The DVD drive is from an old Packard-bell running Windows XP SP2, but I have no idea what wavelength and power the laser is (from what I've heard its a 660nm at 200mW+ and an 808nm whose power I don't know but I really have no idea).
I would like to make a cool handheld laser with a nice host and a click on - click off switch without it costing too much (I've seen some places sell hosts for £50 with just the host and a heat-sink holder). I need a list of parts needed and where to get them from and what tools will be needed too. Below is what I have so far (not much right now... not much at all!)
I really appreciate all the help you can give me, it would be awesome to build my very first laser! Thanks in advance

I just had a look at the DVD drive, here's a picture:
The writing is as follows;
EAN CODE (followed by a bar code)
Yellow sticker (left): CAUTION - Class 3B visible and invisible laser radiation when open. Avoid beam exposure.
Yellow sticker (right) CLASS 1 Laser Product
White Sticker (japanese text, followed by
NEC Corporation
7-1, Shiba Go-chome, Minato-ku Tokyo, JAPAN
DVD R/RW & CD -R/RW DRIVE
Model ND-6500A (next to it is a circle with a dick inside, with "N56" next to it)
Power Supply 5v
Made in China (lol thought it was japan
) US pat .4,615,023
Underneath is a box titles PBR and says
SERIAL No. 5408198C123
MANAFACTURED April 2005
Then there's the logos; CE, some arrow in a circle, backwards RUus and some legal stuff.

I'll get back to you once I've found the manufacturer and model of the drive
