The project construction site in Wuhan East Lake High-tech Zone Great Wall Innovation and Technology Park, covers an area of 100 acres. The company's existing production plant 8000 square meters, with research and development and testing experiment hardware and Conditions. This project to add a building area of 8,000 square meters, without further expropriation of land for construction in the building of a company's existing address. Production, research, testing equipment list (import part of domestic production and auxiliary equipment procurement) to hear the word of the laser, we may be a bit scared, because it is reminiscent of Final Fantasy Star Wars weapon, or the operating table on the doctor's scalpel. However, the laser weapon does not always hurt, it also exists in our daily lives. This special design can avoid the mistaken operation of   green laser pointer , especially under the condition the customer doesn’t know.
For example, the laser (Laser), the hologram is laser technology application in reality, our lives have brought great convenience. Original laser and we so close to the original Chinese name of the laser called "Laser", "les" is a transliteration of the English name of LASER, is from the first letter of the words in the English Light Amplification by Stimulated Emission of Radiation composed of abbreviations. Means that the stimulated emission, optical amplification. What is called "stimulated emission"? It is based on the great scientist Albert Einstein in 1916 proposed a new set of theories. This theory is that the atomic composition of the material, a different number of particles (electrons) are distributed in the different energy levels of particles on the energy level by a photon excitation. All customers speak highly of the high performance and good quality of this kind of  green laser pointer .
(Transition) to the low energy level, then will radiate excitation light of the light of the same nature in a particular state, a low light to stimulate the phenomenon of a light jump from high energy level. This is called by the stimulated emission of light amplification, referred to as laser. A scientific theory put forward to achieve, often a difficult road. Einstein proposed this theory as well. It is a very long time to be set aside in a drawer nobody cares. 1950 Bordeaux, a secondary school teacher Alfred Kastler and Jean Brossel the invention of "optical pumping" technology. This invention was later used to launch laser, and in 1966 he won the Nobel Prize in Physics. This kind of  green laser pointer is a good assistant of the teachers, trainers, expert, scholars, professors, lecturers and businessmen.
