Presumably the system would be completely self contained. Neither the laser nor the fluorescing being visible. Maybe we can think of the fluorescing as a mechanism to conduct heat from the electronic components to the case of the NVG. Of course that would heat up the NVG case but perhaps it is not emitting in the iR anymore than the person's face underneath it. More info is needed.
I've seen multiple posts like this one, and they all seem to be missing a huge point (maybe I'm getting trolled?
From the article (sorry, I read it):
"...starting from 290 kelvin. We use a pump laser with a wavelength of 514 nanometres, and obtain an estimated cooling efficiency of about 1.3 per cent and an estimated cooling power of 180 microwatts."
Where the hell is all the heat going if you stick this thing inside some goggles with the direct purpose of cooling something inside said goggles? That question has nothing to do with the above quote... it's there to drive it home - look at how inefficient this process is!?! I'm sure it's extremely useful and interesting for a great many cases, but I don't see (pun) how this is good for night vision goggles.
I keep picturing a guy on a sailboat blowing really hard on his sail.
