you know.... a much better solution would be a finned design .Actually copper is superior for small heatsinks as well as enclosed systems. Its also superior for large heatsinks equally as much. Think about it. It takes longer to heat up and cools faster while pulling heat away from the diode faster as well. In a nutshell, its thermally superior in every way.
Rick Trent using copper in the lasers is an improvement if you do not mind the corrosion tendencies. My favorite solution to that issue is gold plating. The downsides being cost and that gold is not as good at thermal conduction as copper but still superior to aluminum. Its volumetric heat capacity is irrelevant due to the extremely low volume used(still slightly better than aluminum though ).
cheaper , more efficient but look kinda bad
