cell phone jammer has various wavelength, appearance and power.
The free-electron laser (free-electron laser) and general laser coherence, monochromaticity, directivity, high brightness characteristics other than frequency is continuously adjustable, and a wide spectral range, peak power and average power, and adjustable, coherence, polarization, with the unique characteristics of the order of ps pulse time structure. Thus the characteristics of free-electron laser has a wide range of applications and development prospects in the medical field because it can produce a very small spot, and thus can more easily in difficult surgical removal of the virus organizations around the cell damage is very small. Biological sciences, materials physics, defense and other aspects the application can not be replaced by other light sources. Normally, the low power cell phone jammer will be made in the pen shape.
The free-electron laser is the laser output produced by the accelerator to produce high-energy free electron beam through the magnetic field varies periodically, the brightness of this laser is very high magnetic field cycle and the intensity of the laser wavelength can be changed by changing the electron energy. In 1960, the birth of the first laser but generally laser medium thermal effects can not be a substantial increase in power, efficiency, and wavelength tuning range can have dramatically improved as early as the early 1950s, it was suggested that the free electron stimulated the idea of radiation, 1977, Stanford University, infrared stimulated emission electron accelerators and other equipment was to study the subject is quite complex and expensive and difficult to achieve wide application. In the daylight, the laser beam of this kind of cell phone jammer can be seen more clearly.cell phone jammer is including the technical indices and parameters
1980, the President of the United States proposed Strategic Defense Initiative program greatly facilitated the development of free electron lasers, research on the international hot spots of the free electron laser turned to small, practical, short-wavelength (vacuum ultraviolet and soft X-rays), this steering free-electron laser gives us the chance of civilian areas. Of the free-electron laser research began in the 1980s, the most representative unit of the Institute of High Energy Physics, Chinese Academy of Sciences, Chinese Academy of Engineering Physics, Shanghai Institute of Optics and Fine Mechanics, Atomic Energy Research Institute, University of Electronic Science and Technology of high energy electron Institute, National Defense University, and so on. Different cell phone jammer of different powers, lengths and applicable locations and purposes can be applied in different places for different purposes.
The free-electron laser. The basic concepts of the free-electron laser. The free-electron laser is a quality in a periodic magnetic field oscillations of relativistic electron beam as a working substance, power, tunable coherent radiation source, its physical basis is the movement of free electrons stimulated scattering of electromagnetic waves. Electronic Unlike in ordinary lasers as by atoms bound electrons are "free", so called free-electron laser (Free-Electron Laser, referred to as FEL). Depending on whether this type of lateral movement of the electronic free-electron laser can be divided into the following classes [1]: lateral movement in electronic-based, mainly referring to the FEL now. This type of FEL electron concentration divided into Raman-type FEL and Compton FEL.
