The lightsaber in Star Wars is not a laser sword!
The official setting of the lightsaber is the ion beam bound by the magnetic field excited by the crystal. In reality, if such a strong magnetic field is used directly, it will be more lethal than a sword. Of course, real laser weapons are not so jokes, this is a directed energy weapon that uses a directed laser beam to directly destroy the target. At present, the US and British navies are cooperating to develop electromagnetic guns and laser weapons that are actually equipped with large ships at sea. China has also publicly demonstrated small laser weapons and equipment that can strike low-altitude drones. Germany has also used this technology to conduct a strike test two years ago and achieved success.

The energy of this Laser pointer is only 1 to 5 milliwatts. Although not cool enough, if you look directly at the laser beam for a long time, it will cause damage to the retina. Therefore, as long as it is not titanium and krypton gold eyes, this kind of laser pointer is still very dangerous to shine on the eyes! What can a higher energy laser do? A laser of 5 to 10 milliwatts can be used as a CD drive; a laser of 100 milliwatts can be used on high-speed CD-RW burners; a laser of about 250 milliwatts is often used on DVDs. In fact, the answer is very simple. If you try to intersect two beams of light, will they collide like an iron sword? Not only will it not, if there are no obstacles (opaque objects), the two powerful laser beams can still travel through the sky, and will not only remain more than one meter in length in the air. In fact, lightsabers and lasers have nothing to do with each other. What is plasma, we will talk about it later. I’m very responsible to tell you that a cool lightsaber like the one in Star Wars can’t be made by laser alone. So when you watch Star Wars next time, don't say "Laser Sword" again!
