I am working on a project to laser heat a Stirling Engine with a generator mounted to it. I have available 4.5 to 5 VDC and 20 mA. What parts would give me the highest temperarure beam? I am not too concerned about cost in trying to prove a concept but I am financing this out of my own pocket. It has been explained to me that the beam itself has no temperature until the photons have been absorbed. Any advice on how to achieve the highest temperature with only 5 vdc and 20 mA would be most appreciated.
