    Cool Laser
AI Thread Summary
Laser cooling from a significant distance poses substantial challenges due to the dispersion of laser light and the need for precise targeting. The effectiveness of laser cooling diminishes with distance, making it impractical for large-scale objects like planets. While laser cooling is feasible in controlled environments, such as laboratories, achieving noticeable effects on distant objects would require immense power and size. The discussion highlights that while cooling is possible when in close proximity, the threshold distance for effective laser cooling remains unclear and likely very limited. Overall, the concept of cooling large celestial bodies with lasers remains largely theoretical and impractical with current technology.

Just wondering If it is possible to laser cool an object from afar or from a large distance away? Suppose you wanted to laser cool a planet with satellites in orbit around it, Would that be possible? Doesn't matter If they'd have to be ridiculously huge to have a noticeable effect or would take a very long period of time, Just wondering If it's possible. If not, then what is the threshold distance you can laser cool from if any?

I can't see any way that it could be done at all. Do you know how laser cooling actually works?
 
I do but I've only heard of it in the context of super-cooling, like very near absolute zero.

In that regards it more or less gives very low energy electrons nowhere to move, but only very low energy before it is employed.

Can you cool an object with laser if you are close by?
How would you do it?
