Edit: Laser diode info page
I have a basic question about laser diodes. For a 14-pin butterfly package as shown below. I know that I need to control the current going in to the laser diode, but I don't know about the voltage. Should the voltage on anode(11,13) to cathode(3,12) be regulated? Or is it okay if the voltage is below the maximum ratings after the current is limited? Thanks in advance.
