OK I posted this on LPF and got no takers. I really should have come here first but hey live and learn.
this is a 100mW Suwtech lab laser I refurbished. It supports both TTL and analog modulation. The beam is a nice stable Gaussian Tem00 (or as close as I can tell )
The cable in this picture is the one you get. the makeshift one seen in other pictures is just a cable I made to monitor the current.
when I first got this laser it only did 89mW and would drop to 75 after a minute.
I replaced the fan and re tuned the driver to make the laser stable. (the diode and TEC pots had already been messed with )
as you can see the laser is now back to spec wile the diode current is still well below rated operating current
