Nice job. You certainly shouldn't have any problem with cooling. Are you adding any additional corrective prisms/lenses?
There is some intentional space that could be used for extra optics.
But I become less and less convinced of their necessity ...
What collimators are you using?
wow, a very nice setup!
Will there be three phase!!!!
Nice, How did you ensure you don't have a thermal short around the TEC?

I tried a few but I guess I'll settle with the o-like.
@dnar
I use 4x simple TO-3 isolation to prevent thermal conduction.
Nice idea! Thanks.
