Weather thermal laser cutting

First of all, it depends on the actual power of laser weapons. Secondly, laser is easily affected, especially by weather conditions, such as fog, rainstorm and snowstorm, which will seriously weaken the actual efficiency of laser. At present, there are reports that laser weapons can be used in actual combat. As for what you said about "cutting objects by emitting effective frequency into the cosmic layer", it is more difficult to cut objects by emitting laser from the ground to space, because the earth is constantly rotating and revolving, and it is not easy to gather on the surface of objects, and because the earth's atmosphere is thick, the actual efficiency is greatly reduced after the laser penetrates the atmosphere. Of course, if the laser weapon is powerful enough, the cutting distance is not too far, and it is easy to aim for a long time, and the volume is not too large, it can still be cut (if you want to cut the moon or the sun, it is obviously impossible at present).
