The quality improvement of cell phone jammer

 The quality improvement of cell phone jammer should be done in a short time. 
"Maiman design" caused the scientific community's shock and suspicion, because scientists have been looking and looking forward to a helium-neon laser. Although Maiman introduced the first practical laser scientists in the field, but in court, on in the end who invented the technology debate, once aroused much controversy. One contender is the "Laser" ("stimulated emission type optical frequency amplifiers," the acronym) ? Gordon Gould, inventor of the term. He studied at Columbia University Ph.D. 1957, made the word. At the same time, the inventor of the maser Townes and Xiao Luo also developed the concept of the laser. Final decision by the court, Townes paperwork for research in Gould as early as 9 months to become the winner. But Maiman's invention of the laser power has not been shaken. December 1960, Iranian-born American scientist Jia Wan rate finally succeeded in making people and running the world's first gas laser - He-Ne laser. In 1962, there are three groups of researchers almost simultaneously invented the semiconductor laser. In 1966, scientists have developed into a range of wavelengths can be continuously adjusted in the organic dye laser. The quality improvement of cell phone jammer is still in the process.Early ruby laser is used as the excitation source common source. Now the production of ruby laser has developed many new products, categories also increased. In addition, incentives, also divided into several, in addition to optical excitation, there are discharge excitation, thermal excitation, and chemical and other incentives. The construction of the manufacture base of cell phone jammer is still in the process.Also commonly used in solid-state lasers yttrium aluminum garnet laser, it's working material is alumina and yttria synthetic crystals, and mixed with neodymium oxide. Laser is the neodymium ions in the crystal release, the human eye can not see infrared light, can work, can also be pulsed manner. Because of this the laser output power is relatively large, not only militarily useful, and can be widely used in industry. In addition, yttrium aluminum garnet laser in the laser or liquid dye laser, cataract and glaucoma treatment is very effective. There are also two more special laser. One is the carbon dioxide laser, can be called "stealth" because it sends a laser wavelength of 10.6 microns, "body" at the infrared region, the naked eye can not perceive that it works with continuous, pulsed two. Connection produced by the laser power up to 20 kilowatts or more.
