Stargazers use green laser pointer to point at the stars

Stargazers use green laser pointer to point at the stars.
At present, high-end laser cutting, welding equipment is monopolized by foreign manufacturers, the competition is very fierce. China's laser processing systems market is also growing year by year,

with the development of the national economy following the 1993 to 2000. From Table 1.1 we can see that the output value of China's laser processing system 2000 is about 340.55 million yuan, the

relative increase of 114 percent in 1998 can be said that the application of surface soon. It can be seen, the rapid development of China's electronics industry has brought a huge boost to the

laser processing industry in China; the same time, China's laser processing system has improved steadily improve the quality of China's electronics industry has brought good news. green laser

pointer will not disturb others stargazing if it is not used continuously for a very long time.
This does not need to buy expensive imported laser processing equipment, to run, maintenance, parts replacement, maintenance, service brings about a lot of convenience. Different applications of

laser processing in China with foreign, for purposes of comparison, the 2000 application is shown in Table 1.2 can be seen, laser marking (marking) the proportion of the very important position in

the field of laser processing . From China's 2000 total sales of 340 million yuan, compared with $ 2.87 billion abroad in 1998 total sales, indicating the important industrial areas of China's

laser processing system for technological transformation of traditional industrial space. The charger of battery of green laser pointer can be bought easily in the ordinary store.
The use of advanced laser manufacturing systems will be difficult to deal with China into the WTO brings the impact of foreign products on the Chinese market from the market development fully

demonstrates China's laser processing systems there is considerable room for development. Laser cutting technology Review of laser cutting is the most important one in the laser processing industry

applications, the application of the first laser processing, most of the processing methods. It accounted for more than 70% of the entire laser processing industry. Laser cutting and other cutting

methods, the biggest difference is that it has the characteristics of high-speed, high precision and high adaptability. Also has a thin kerf, a small heat-affected zone, the quality of the cutting

surface, cutting noise, the kerf edge of the vertical, smooth trimming, cutting process is easy to realize the advantages of automation control. Some high power green laser pointer has an obvious

heating effect.
