473nm CNI lab power supply + TEC adjustment?

Does anyone know how to adjust the power supply and TEC controller for those 473nm OEM B+W labbies ? The TEC controller is LDTEC-12, but there is also a board on top that says "MIC-CON Ver 4.0". On PL some people have provided the pin-out for the controller. However, I'd like to be able to adjust the power and temperature control point.

Location of pots. Only #1 is accessible without removing the top board. Also the top board is made to not connect to the connector at #4. Any idea why?

If anyone has any insights, please let me know. I was thinking this might be useful for a higher powered green using some O-like crystals and the 808nm laser in the CNI labbies.

I haven't tried playing with the TEC on these, so that I could not tell you..

A simple solution though may be to add a trimmer in series with the feedback
from the thermistor? IIRC they are 10k and a quick setup should verify weather or not
it would work..

Are you looking to cool it down more, or increase the temp?

I converted one of mine to a 532 with a bonded set which works fine, but if you plan
on using a 2 piece set, you have to change out the OC mirrors as well...

Well, the power supply was originally for a 473nm DPSS laser. However, I've taken it apart (it was malfunctioned anyway) and would rather use the optics and the perfectly good TEC controller to power a high-powered green DPSS laser, using some of the larger crystals provided by O-like. Then I'd get a nice stable, powerful TEC-temperature controlled green laser using a high-end power supply.

Well that's the theory anyway.

I'm just not sure if the power supply is automated or if I need to set the temperature to the correct level for the crystals, especially as the crystals and their properties are different than those in a 473nm laser.


On another note, I'll have to check out your work with these lasers. It looks like you've done quite a bit on them and it should be some good info to read through.

Badger, do you have the 473 nm head still with everything in it?

I might be interested in buying it. :eek:
