#174786 - CURRENT Responding to: ???'s previous message |
The laser diode is CURRENT driven, and driven very close to the limits too. Voltage control will not work. There are plenty of driver designs on the net - just try looking for one. Laser diodes are also very voltage sensitive too, and brief spikes will destroy them.
