[Laser] laser diode data sheets ?

[KY1K]

Steve,

Some of the later laser diode have improved fabrication and processes 
used in their manufacture. It is possible to use these newer types of 
diodes with only a limiting resistor, which is what your laser pointer does.

Be careful with the voltage and heat sink the assembly as much as 
possible, and it will operate well. Don't try to get more power out 
of them though...or the laser will turn into an LED.

Enjoy.
