Researchers Use Lasers For Cooling

Posted by samzenpus on Wednesday January 23, 2013 @03:04PM from the keeping-it-cool dept.

MatthewVD writes "Infrared cameras on satellites and night vision goggles could soon use lasers to cool their components. According to the study published in Nature, researchers in Singapore were able to cool the semiconductor cadmium sulfide from 62 degrees fahrenheit to -9 degrees by focusing a green laser on it and making it fluoresce and lose energy as light. Since they require neither gas nor moving parts, they can be more compact, free from vibration and not prone to mechanical failure."

A proper scale? Shouldn't it be in Kalvin then?

Researchers in Singapore were able to cool the semiconductor cadmium sulfide from 290 Kelvin to 250 Kelvin
Fixed your fix.

No, it should be in Hobbes.
