Rumors about the creation of small-arms laser weapons in the Middle Kingdom will not have to be denied, because with the existing level of technology, it is simply impossible to create them. This is the position of the expert invited by the portal Styropyro to comment on the news that appeared a few days ago. The main idea: the creation of a portable laser is much more complicated than the construction of a whole laboratory.
The first controversial issue: what is the wavelength of this laser? The leakage tells about the miracle-radiation that passes through the glass and ignites the clothes and burns the human skin. However, these are materials with very different properties, and if with the help of a simple infrared laser we really can set fire to the sulfur head of a match, then it will not do anything human flesh. At best, such a ray will blind a person, which is explicitly prohibited by the Geneva Convention on the use of laser weapons.
Next, using the Stefan-Boltzmann law, it is relatively easy to calculate the power that will be required to fire a soldier's clothing at a distance – slightly more than 640 watts. But how to get so much energy if we are talking about a compact rifle weighing 3-4 kg? Shoulder backpack with batteries for a couple of shots? More strangely, it's a rumor about the ability of a laser rifle to set fire to gasoline or other fuel from afar. Just watch the video:
However, it is impossible to completely exclude the appearance of super-powerful and simultaneously compact batteries, which will ensure the proper result. But then who would be interested in the laser rifle, if these batteries themselves – the greatest breakthrough since the invention of the wheel? Alas, even the advanced battle lasers of the armies of the world still look like sheds on wheels, so to the desired level of miniaturization is very, very far.js.src = “&version=v2.8”; 'script', 'facebook-jssdk'));
