[Laser] laser diode data sheets ?

[steve kavanagh]

I've picked up a few cheap laser pointers (CDN$1.95!)
and am wondering about proper drive for the diodes. 
There is no driver circuitry in the pointers, just a
68 ohm series resistor in series with the 3 LR44 1.5V
cells and draw in the vicinity of 30 mA.  The label
indicates that the output is less than 1 mW at 630-680
nm.  

Does anyone know where I can find a data sheet for a
diode or diode module of this type so I can better
understand what I should be doing with these diodes ? 
I've spend some time searching the web and can't find
any data sheets for diodes at this power level.
