Cooling with Lasers....

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

Oh that is so cool! Thanks.

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! :crackup:

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?

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.
