The working time of laser pointer can be very long

The green ray laser pointer will play an important role in the teaching process.
The global laser processing industry and market Development of an overview of the laser and laser processing is a fast developing high-tech, has become one of the key technology and equipment of the development of new industries and transform traditional manufacturing. A variety of laser (marking, welding, fine-tuning, drilling, cutting, scribing, heat treatment) systems, equipment, have been or are entering in various industrial fields, such as electronics, light industry, packaging, gifts, hardware, industrial, medical equipment, automotive provide advanced technical equipment, machinery manufacturing, steel, metallurgy, oil, etc., for the modernization of the technological transformation of traditional industries and manufacturing. The past 20 years, China's reform and opening up and rapidly developing market economy, greatly promoted the high-tech R & D and applications. The working time of laser pointer can be very long.
Laser science and technology and laser processing is one of China's rapid development of high-tech industries. So far, the country engaged in the manufacture of industrial laser systems company of over 100, is a research and development, mass production and supply, sales, maintenance service system. The supply of domestic lasers have been able to mass, low power (30W-500W) Nd: YAG laser processing system equipment and high power (100W-5kW) CO2 laser processing system equipment. Domestic industrial laser manufacturing enterprises have been able to small quantities of low, mid-range laser marking, scribing, welding, cutting, drilling and other equipment. Lasers and laser technology, the initial size of the industry is taking shape. According to the statistics of the laser Branch of China Optics and Optoelectronics Manufactures Association (COEMA) [10], the 2001 laser processing system equipment production to 630 million yuan, an increase of 86% in 2000. The test data sheet of laser pointer should be renewed.The customer has stated the color choice of laser pointer in the order
Laser processing system equipment production in 2002, the first time exceeded one billion yuan to 10.355 billion yuan, than in 2001, an increase of 65%. [1] According to statistics, the global laser processing market in 2002 sales of $ 2.99 billion (about 26 billion yuan), both compared to about 1/26. In China there is a huge laser processing applications market, and global manufacturing base in this market due to China's accession to the WTO since the country is rapidly formed by the rapid growth.
