Here is a small little article I came across that explains how lasers can be used to cool solids. Their first experiment managed to cool a solid only 0.5F, but one of their more recent attempts succeeded in cooling the same solid 117F! Near the end of the article, they suggest applications in cooling modern semiconductors. Sweet! |

Interesting, but as stated HERE (PDF file), this only applies in a vacuum environment.
It could be done as stated here . I'd certainly look forward to cooling a CPU to -100 deg C. |

He he... we wouldn't need cold cathodes anymore

Speaking of cold cathodes, though, that is a similar technology to what is being proposed by another company. Basically, they take semiconductor fabrication techniques to create very thin vacuum filled gaps. Then, applying current across the junction causes heat as well as electrons to move. Voila! A potential competitor to the peltier device, but (hopefully!) much more efficient. Efficient enough to compete with standard refrigeration, perhaps!
Now, THAT is what I'm looking forward to! |

the thing that brians256 is talking about is called "Thermotunnel technology" its being engenered by a company called cool chips. as far as a lazer cooling goes that would be pretty cool stuff to watch anyways

exchange : will give one NEC he-ne 1 mW laser tube with power supply and a case of beer for one NdYAG laser (power supply appriciated)

Only in a vaccum? So how much room do you need? I mean, could you have the plate which holds the vaccum 1mm above the processor, and it still works?

Did you read where it said that the max power transferred was some ridiculously small number? This is not even proven to work as well as blowing hard on a wet towel.
