Based on laser-produced by stimulated emission. Describe the basic principles of stimulated emission, why can produce optical amplification? And to CO2 and YAG laser as an example composed of three

essential parts of the laser. Some have a metastable energy level structure of the material, in certain external energy such as solar energy, electrical, chemical and other excitation, allows low-

level atoms or ions from the excited to the high energy level. Under certain conditions, can lead to high-energy state in the number of atoms is greater than the number of atoms in the low-energy

state, this state is called "inversion." Details of outsourcing of green laser pointer needs to be discussed further.High power density laser by laser processing system under the control of the

CNC, designated parts of the metal surface scan, instant heat up the surface so that part, then use the excellent thermal conductivity of the metal itself, so that the surface is usually much

higher than in the cooling medium to obtain the cooling rate quench, thus changing the surface of the organization and performance parts, metal parts and components to improve surface hardness,

wear resistance, corrosion resistance and strength and high temperature performance.
Its research and development of laser cutting, welding, cladding, and other aspects of laser remanufacturing process results have been widely used in the Mercedes-Benz, BMW, Audi, Volkswagen and

other auto companies and Airbus aircraft company. German company Trumpf fast axial flow CO2 laser series products RF power and Rofin's family of RF slab CO2 laser power, the United States PNA's CP

series lasers are specialized high-voltage switching power supply company to provide. Competition in an invincible position in the domestic leading enterprises are developing a new

generation of industrial laser equipment and its applications: fiber lasers, ultraviolet lasers and precision processing equipment, high-power semiconductor lasers and welding, heat treatment

equipment, high-power disc laser and welding equipment, high-power gas laser welding and cutting equipment combinations. Batch sales of green laser pointer are popular.
In short, as China's shift from a manufacturing power to a manufacturing power, laser processing technology, more and more attention to the manufacturing sector, the domestic large-scale, heavy-

duty companies are increasingly concerned about the progress of laser processing equipment, China's laser processing industry of tomorrow must very bright.  
U.S. Coherent (Coherent) in early 2001 will be sold to Israel Medical Laser Group ESC / Sharplan company, purchased a few engaged in manufacturing industrial laser company, monographs in the field

of industrial laser technology research and product development.
