Many laser diodes are packaged with a photodiode that gets the mild from the laser's again facet. This allows setting up a manage loop to drive the laser in a constant output power mode rather than just setting a steady current. I'm attaching a image of a motive force circuit i discovered on line. Would this be a appropriate motive force circuit for this laser diode? I'm no longer for sure on the specifications of the diode however i'm guessing it is more than 100mw.
