One thing I did wonder, I am trying to get the best dissapation of heat as I can without resorting to TECs or active cooling, is it best to have the host a direct press one, where I will pressfit the diode right into the host itself (which is made out of aluminum, and also, will anodization help in any significant way to aid heat convection?)
or would it be better off to make a 1" wide copper module that will house the lens and the diode itself, and just pressfit it into the host?
More or less my question is, direct press host VS pressfit copper module, which would be better to achive the most effective cooling without resorting to thermoelectric or active cooling?
My own thinking is that a copper module will work better, as it dissapates heat 2X faster then aluminum, but the thing that puzzles me is that while it dissapates faster, there is now a new layer between the copper and aluminum, which might create losses the copper was supposed to make up for. but I am not certain to which one is the correct method.
Here is the laser head and if the module the better option, it will sit flush with the head. This head is fairly big as it is, but I would like to make the best out of it. (I will most likly use it either for a ~2W 445, or a high power pump doide for a green).
Thank you for any help.
The head is roughly 2.5" in daimeter, and the top "stage" bieng ~1.5" so room for a module is no issue.
