The power of torch-like green laser pointereven reaches a laboratory grade

Development of laser industry abroad. Development of laser industry abroad, according to "Laser Collection" 1997 report, the world laser market can be divided into three regions: the United States (including North America) 55%, 22% Europe, Japan and the Pacific region accounted for 23%. Japanese market in the world of laser technology top the list in optoelectronics, the United States ranked second; in medical laser and laser detection is the United States top the list; in laser materials processing equipment is Germany top the list. Therefore, we chose the United States, Japan, Germany three countries to present their development of laser industry, laser market will reflect the basic situation of the world and its development trend. The largest difference between two types of green laser pointer will be demonstrated.
Development of the U.S. laser industry has yet to see the full description American Laser - Optoelectronics Industry Development of the complete data are only based on the literature reviewed. 1994 U.S. Optoelectronics Industry Development Association, the 1993 World Laser - Optoelectronics market were Statistics, with a total of 750 billion U.S. dollars; U.S. Optoelectronics Industry Development Association to monitor, optical storage, optical communications and optoelectronic technology industry known as a hard copy, and that This area is now Japan's dominant position in the $ 75 billion value of about 50% in Japan, the United States should be aware that the current development of optoelectronic technology industry, the United States in this area can account for a large share. The color is one of the biggest different points of these two kinds of green laser pointer.
The following describes the United States of laser processing and laser medical aspects of the development. According to the 1996 "Industrial Laser Review" magazine in 1995, worldwide sales of laser processing system about $ 1.1 billion, the U.S. accounted for 31%, Europe 32% Japan 35%, other 2%. More well-known in the U.S. laser companies: Coherent, Spectra Physics Inc., United Technology (URTC) company, PRC company, Combustion Engineering, Lumonics Corporation, Synrad company, Marted Lasers company, Electrox Company and ESI Corporation. Coherent and Spectra-Physics laser two largest U.S. companies, accounting for U.S. laser company more than 40% of total sales. As for blue ray green laser pointer, several finished products must have come out.
Spectra-Physics Department of the company's industrial laser of high power CO2 lasers equity Rofin-Sinar in Germany has acquired the company, mainly produces 1.5kW-6kW cross-flow CO2 laser. Joint technology company mainly produces iodine laser wavelength of 1.3 microns and solid-state laser diode excitation UV excimer lasers. Now more than carbon dioxide laser power of 500W, and in theory up to 100KW, recent reports have reached 20kW. And its power is bigger, the better, so the Japanese research and development of the carbon dioxide laser to send to expectations. Carbon monoxide laser power industry to create the Institute of Japan jointly developed with Mitsubishi Heavy Industries, 89 years to achieve a continuous four hours 5kW, 7kW short period of oscillation output. The appearance of green laser pointer is closely related to the development of the materials.
93 years of its output power has reached 20kW, it is cutting welding Chiang Kai-shek to emerge, and the high-power iodine laser is the Japanese industry to create research and Kawasaki Heavy Industries developed together in 1989 and a near-infrared oscillation, which is the chemical laser, characterized by high efficiency oscillation, 5kW CO laser, 1kW iodine laser device has been set up in April 1992 established the laser application engineering center. In addition, the arc lamp excitation solid laser amplification are 3kW, because there is increased power led to beam divergence angle is too large and low pulse repetition frequency oscillation drawback, Japan is trying to develop semiconductor excitation YAG laser to replace it. This kind of red ray green laser pointer  have three functions.
