What are the other uses of lasers in life?

Unlike the illustrations in anti-aircraft missiles or science fiction movies, laser hits will not cause an explosion. The difficult task is that the light beam must illuminate the same point within a certain period of time. In this case, it is the rear wing of the drone. They caught fire and the object crashed. The video clearly shows how the tail fin was sawn off by the jet. Describing electromagnetic radiation with mathematical precision is not easy. It is often helpful to think of radiation as consisting of a single wave train. This wave train is characterized by fixed wavelength, length and position. For lasers, a single wave train may be very long, and wave trains adjacent to each other will vibrate synchronously. This characteristic is called coherence and is a prerequisite, for example, when 3D recording of an object is to be performed.
