Default 3 Color Scanner (Need diode specs...)

I'm going to attempt to build a 3 color scanner using red, green, and blu-ray (violet) lasers. It will either use 2 or 6 servos and will interface with computer via usb.

To best control them, I will have to make drivers for the diodes that support PWM and in order to do that, I need to know:
turn on voltage
rated maximum voltage
specific bias current
behavior of the monitoring pin

DealExtreme: $44.04 100mW 405nm Blue-Violet/Royal Purple Laser Pen (2*AAA)
LP650S 100mW Red Laser Pointer (Black) - Focalprice.com
30mW Green Laser Pointer Pen (Black) - Focalprice.com

Anyone have advise for where to find spec sheets on the diodes in these pointers?

Thanks.

I think the br diode is GH04P21A2G

the red might be either GH06P24A2C or GH16P24A8C

and I still have to figure out what the green could be.

What are the servos going to control?
