The economical efficiency of green laser pointer is very high

Now employs more than 1,400 branches in more than 40 countries and regions around the world set up a marketing and technical services, sales of $ 372 million in the 2004-2005 financial year. 2001, Rofin Group under the business reorganized into three core business groups to respond to growing market demand and system integrators need to meet individual customers. High-power business group products are mainly for material cutting, welding, surface modification of high power CO2 laser, solid-state lasers and semiconductor lasers. Rofin-BaaselChina inception, namely to serve as a pilot to expand business in China.  green laser pointer can be utilized to scare the dangerous animals.
Now to set up service branches in Shanghai, Shenzhen and Chengdu, and the establishment of adequate supplies and spare parts inventory, with an experienced, technical and comprehensive after-sales service and rapid response team. Laser (Laser), the original intent of the stimulated emission amplification of the light, it is the abbreviation of the English (Light Amplification by Stimulated Stimulated Emission of Radiation), laser science, the combination of many scientists to create wisdom from its conception to start-up and development , including the pioneering work done by the American physicist CHTownes and ALSchawlow especially basic research in the field of quantum electronics, leading to the invention of the maser and laser.  green laser pointer can be used to lighten the match or flammable materials.
The world's first laser the Americans Maiman (THMaiman,) made of ruby laser at the Hughes Laboratory in California May 15, 1960, it is the three-level system, ruby crystal light-emitting materials, with luminosity high pulse xenon lamp excitation source in human history, the first laser beam, the wavelength of 694.3 nm. realized Townes and Xiaoluo, predicted in 1958. Townes (Townes, Charles Hard, born in 1915) - U.S. physicists, quantum electronics research and invention of the maser, won the 1964 Nobel physics prize. He was born in the United States South Carolina Greenville, State University of Fuhrman graduated from Greenville. For this kind of green laser pointer , the application is various and function is practical.
By the California Institute of Technology Doctor of Philosophy in 1939 at Bell Telephone Laboratories, and taught at Columbia University in 1948. Three years later, he generated the idea of the maser, using ammonia as the amplifying medium, to create the first maser in December 1953. This research has led to the laser by Maiman in 1960. 1967, he was appointed professor at the University of California, created a radio and infrared astronomy program at the school, the results found in interstellar space of complex molecules (ammonia and water). The characteristics of the laser. Spatial coherence and direction of the laser: beam spatial coherence and directionality are closely linked. The divergence angle of the different types of lasers are different. The economical efficiency of green laser pointer is very high.
