Make good use of the green laser pointer

The annual sales income of 1.5 billion euros; Germany, Rofin (after Trumpf industrial laser equipment manufacturer), with annual sales of 1.32 billion euros. The laser is divided into three categories: CO2 laser, solid-state lasers, fiber lasers. The cost-effectiveness of the CO2 laser is much higher than other lasers and wavelength 10 times a very wide range of applications, and future development potential, the world's leading technical authority in Germany Fraunhofer Institute of Laser After decades of laser applications, finds that the CO2 laser will always occupied the high-power laser slab cutting and welding market, not alternative. The CO2 laser is divided into three categories: cross-flow CO2 laser, axial flow CO2 laser, whirlpool CO2 laser. In all, this kind of red green laser pointer is the very useful and practical tool for the customer.
CO2 lasers advantages: simple structure, low cost, easy to operate, the working medium is uniform, good beam quality, and long time stability of continuous work, high efficiency, coherence, etc., the market share of around 60%. The CO2 laser has obvious advantages: First, it has a relatively large power and high energy conversion efficiency from the output pulse energy and power to achieve a higher level. Second, it is the use of CO2 molecule vibration - rotation transitions between energy levels, spectra, there are dozens of lines of the laser output in the vicinity of 10 microns. Third, the output band happens to be the atmospheric window (ie the atmosphere to the high transparency of the wavelength). The laser of green laser pointer is especially clear in the dark night.
Has many applications, such as used in the processing (welding, cutting, punching, etc.), communications, radar, chemical analysis, laser-induced chemical reaction, surgical and other aspects in the national economy and national defense. United States, Russia, Japan, research and development of cross-flow CO2 lasers, high power, low cost, but the beam quality is not very good, mainly used for heat treatment and remanufacturing. National Science and Technology Program in China for many years done a lot of the work of digestion and absorption cross-flow CO2 lasers and axial flow CO2 laser. Germany developed axial flow CO2 laser beam quality, has been widely used in laser cutting and welding, its power has reached to 40,000 watts, and a series of products, with annual sales of more than 5000 units, it each cavity unit for up to tens of centimeters working voltage up to more than 20,000 volts. The sales plan of green laser pointer will greatly influence the following production plan preparation.
Cavity wall is glass, the cavity cooling capacity is particularly poor, requires the use of the power consumption of tens of kilowatts, the price of more than 20 million of the Roots blower. The axial flow CO2 laser complex structure, high cost, high operating costs, high maintenance costs, the SME is difficult to accept and promote the use of slow progress, is clearly not the direction of development of China's CO2 laser. The laser industry in China is only at the manufacturing level, the number of domestic enterprises over the years by repeat purchase foreign axial flow CO2 lasers digestion and absorption, and a joint venture to introduce a total cost of over eight hundred million yuan, is still dependent on imports for more than 65% of the core components of the core technology of foreign monopoly have occupied our laser cutting welding for more than 90 percent of the market. Therefore, the quality and performance of   green laser pointer can be guaranteed.
