Laser surgery is the use of this feature of the laser to remove
Laser weapon has its uniqueness, so it is widely used in air defense, anti-tank, bombers and other military applications of self-defense laser has become a powerful weapon, because it has three levels of destructive power: 1. Ablation effect Laser thermal processing with the same principle, when the high-energy laser beam hitting the target, the laser energy is absorbed by the target material, converted into heat. It is easy to manufacture red green laser pointer .This heat is sufficient to make the target partial or complete perforation, fracture, melting, evaporation, or even an explosion. (2) shock effects such as target material is gasified, the target material will produce recoil effect in a very short period of time, compression wave and the material forming the surface layer of broken crack open, debris flying out further damage caused by 3. goal of radiation effects materials will also form a plasma gasification clouds, can produce ultraviolet radiation and X-rays, electronic components inside the target is destroyed.
Laser energy:
Laser can also be used in nuclear power on. Red green laser pointer is produced with mature technology.Now the world's nuclear power plants built to use nuclear fuel is uranium, the use of tritium fuel studies have not been successful. From the studies, tritium fuel is more resistant than the uranium fuel burn, 1 kg of tritium fuel combustion energy than three times higher than the uranium fuel. More attractive is the tritium storage of nuclear fuel in the earth great. green laser pointer can enlarge the characters in text.1 kg sea water containing 0.03 g tritium on the Earth's ocean water with 1021 kg; or that the Earth's oceans in a 1017 kg on the storage of tritium, it developed a fuel, provided us with the equivalent of 10 trillion billion (1017) tons of coal, enough to spend hundreds of millions of human years, since the tritium fuel so well, why not now? The problem is that it is not easy to achieve ignition and combustion thing. Laser with good tone, with the optical system, it can be focused to a spot diameter of a marginal (less than a micron), which is equivalent to drilling a tiny bit. Some green laser pointer have been inserted card readers.Second, the laser intensity is high, the focus on the focusing of the laser energy density (the average energy per square meter) will be high, ordinary laser of a laser output energy produced can be up to 109 J / cm 2 , enough to melt the material and gasification, leaving a small hole in the material, like a drill bit out. However, the laser-drilled hole is conical, cylindrical, rather than mechanical drilling, which in some places is very convenient.
Laser etching:
Laser etching technology than traditional chemical etching process is simple, can greatly reduce production costs, can process 0.125 to 1 micron wide line, very suitable for VLSI manufacturing.
Laser surgery:
Laser can produce high-energy monochromatic , precise focus, with some penetration, when applied to human tissue generated in the local high heat. green laser pointer is used in daily work and education.Laser surgery is the use of this feature of the laser to remove or destroy target tissue for therapeutic purposes. Including laser cutting and laser resurfacing.
