How to lower power output on laser diode?

laujm:
I am using this particular model from thor labs: http://www.thorlabs.us/thorproduct.cfm?partnumber=QL7816S-B-L

Note that seems to be just a raw laser diode with feed back sensor, so cannot be used without a compatible feedback constant current driver/controller circuit, and as such you could design it to run at any power up to it's maximum limit.
