the laser must have a wider range of applications

In the near future, the laser must have a wider range of applications. The laser weapon is a directional emission of the laser beam directly damage the target, or the failure of directed energy weapons. Depending on the operational use, the laser weapons can be divided into two major categories of tactical laser weapons and strategic laser weapons. Weapon system by the laser and tracking, targeting, launchers and other components, the commonly used laser chemical lasers, solid-state lasers, CO2 lasers. Other characteristics of the laser: laser has many features: First, the laser is monochromatic, or single frequency. Some lasers can produce different frequencies of laser, but these lasers are isolated from each other, and separate use.The picture above shows the basic principle of laser forming: laser metal forming using metal powder as a filler, metal powder through a powder nozzle was sent to the molten pool created by the laser beam. Three-dimensional optical modeling techniques (SLA). SLA technology, also known as light-curing rapid prototyping technology, the principle is the computer-controlled laser beam on the surface of photosensitive resin as raw material point by point scanning, scanning area (approximately tenths of millimeters) thin layer of resin and curing light polymerization form parts of a thin layer.
Nitrogen processing room to ensure the security of the sintering process, the high cost of processing. The process to produce toxic gases, pollute the environment. Laser cladding forming (LCF). Laser cladding, also known as laser cladding or laser cladding, the rise in the 1970s with the development of high-power lasers, a new surface modification technology. Surface of the alloy powder or ceramic powder with the base body in the role of the laser beam rapid heating and melting, the beam away since the shock cooling the formation of the dilution rate is very low, and substrate material was metallurgical bonding surface coating, significantly improve the substrate surface resistance wear, corrosion, heat-resistant, anti-oxidation and electrical characteristics of a surface hardening method.
Only need to scan the laser beam and cutting edge of each layer, but do not have to like the SLA technology to scan the entire surface layer. The device uses a special roller paper, the connection of the paper is heated by the heating roller, then use the laser to cut the paper, the heating roller automatically leave the paper by a laser cut into level requirements of shape. The most commonly used foil is a one surface coated with a hot melt resin adhesive paper. In the the LOM molding machine, the foil was pulled out by a feeding reel, plastic face down through the modeling platform formation received in the other rewinding reel rolled up. The worker is in charge of the manufacture of green laser pointer .
