Default Cooling with Lasers....

Recently saw this interesting article on research and
experiments on using NIR Lasers for cooling...

Sincerely investigate any of these three short quotes as new concepts and you've taken your first step into a larger world:

"I regard consciousness as fundamental. I regard matter as derivative from consciousness..." - Max Planck. "Everything we call real is made of things that cannot be regarded as real" - Neils Bohr. "What we call physical things and events do not exist independently of subjective experience..." - Deepak Chopra.

Each of these three rabbit holes go deep, ending up in the same place.

Default Re: Cooling with Lasers....

I knew about laser cooling from some time ago when everyone was trying to make a Bowes-Einstein condensate. Then later when cooling crystals like the ones in the water. I'm glad it was done at UW, but I think this is not all that new really. Interesting read. Thanks, Jerry.

Very interesting, Jerry, thanks!
It looks like this could be a great new way to keep your beer chilled without dragging the cooler along!

I remember reading about this back when the article was published, really interesting stuff. I'm assuming they are exploiting some kind of anti-Stokes fluorescence?

Default Re: Cooling with Lasers....

Nano crystals huh, if they are driven into a higher orbit by surrounding energy as well as the laser and they emit reddish light, I start thinking about a gain medium that recycles a lasers waste heat, or a way to amplify output.

This was the first time I had read or heard of
using a Laser's beam to create cold rather than
heat.
