Green laser pointer only can be turned off

In the 1970s, the United States carried out two studies: First, Ford Motor Company's body steel plate laser welding; General Motors Corporation, power steering gearbox inner surface of the laser hardening. These two studies to promote the development of laser processing technology in the machinery manufacturing industry in the future. To the application examples of the late 1980s, laser processing has increased the most rapidly growing laser cutting, laser welding and laser hardening. These three technologies has been developed a wide range of applications. Appear in turn to enter the late 1990s, laser honing laser microfabrication techniques in machining has opened a new one. This pulse function of green laser pointer has been attracting more and more customers.
Laser processing technology is the reason why such a wide range of applications, because it has many advantages compared with conventional processing technology: a non-contact processing, there is no mechanical force; Second, the processing of high hardness, high melting point, very brittle and difficult processing materials; Third, the processing zone, heat distortion is very small, the processing of high quality; combination of modern CNC machine tools, laser processing with high precision machining, good controllability, simple procedures, less Province, materials and pollution. Below an overview of several laser processing technology. At present, the laser processing technology has been more widely used, with a very broad market prospects in the national economy and industrial development plays an increasingly important role [1]. The pulse function of green laser pointer is the newly emerging technology.
The essence of laser processing is laser energy transfer to the material being processed, the processed material to the physical or chemical change occurs, so as to achieve the purpose of processing. According to the different mechanism of action between the laser and the workpiece, laser processing can be divided into two categories: one is the laser thermal processing, a laser cold. Laser thermal processing is rapid thermal effects caused by the laser acting on the workpiece surface in various manufacturing processes, such as laser welding, laser drilling, laser cutting, etc.; laser cold laser with the high density of high-energy photon trigger or control of photochemical reactions a variety of processing, also known as laser photochemical reaction processing, such as laser etching, laser doping, surface oxidation. For example, the customer might need the 500mW red  green laser pointer .
A very wide field of applications of laser processing technology, such as machinery manufacturing, textiles, medical equipment, automotive, aerospace, electronics, motor power plant, measuring and cutting tools, metallurgy, chemicals, packaging, measurement, construction and craft decoration and other industries [3]. In the processing industry in developed countries, has entered the era of laser processing. Laser processing in Japan has accounted for more than 10% of the processing industry as a whole; the United States in a leading position in terms of medical laser and laser detection technology, the United States is also the first high-power lasers introduction of the automobile industry the country; in laser materials processing equipment, Germany to go in the world. According to statistics, global laser processing stations more than 5000. The customer can select the most appropriate and suitable power of  green laser pointer according to the real needs and actual requirements.
