Is Long-Distance Laser Cooling Feasible?

[ASGTech]

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?

I can say that it is possible to laser cool an object from afar, but the feasibility and effectiveness of such a process would depend on a variety of factors. Laser cooling involves using lasers to slow down the movement of atoms or molecules, thereby reducing their temperature. This process works by using the photons from the laser to transfer momentum to the particles, causing them to slow down.

In theory, it is possible to use lasers to cool an object from a large distance away. However, the effectiveness of this process would depend on the power and focus of the lasers, as well as the distance between the object and the source of the lasers. The further the distance, the weaker the laser beam would become, making it less effective in cooling the object.

In terms of cooling a planet with satellites in orbit, it would be technically possible but would require a significant amount of power and precise targeting. The size and distance of the planet would also play a role in determining the effectiveness of the laser cooling process.

It is difficult to determine a specific threshold distance for laser cooling as it would depend on various factors, such as the power and focus of the lasers, the size and distance of the object being cooled, and the environmental conditions. In general, the closer the distance between the object and the source of the lasers, the more effective the cooling process would be.

In conclusion, while it is possible to laser cool an object from afar, the feasibility and effectiveness of this process would depend on a variety of factors and would require further research and development.
