cell phone jammer  has been divided into several varieties
Laser weapons 1. Tactical laser weapons laser gun style not much different from ordinary rifle, mainly consists of four major components: laser, actuator, firing devices and rifle butts. However, it can burn a few meters away from the clothes of people, burn skin, and no sound, and often deadly, and in a certain distance, so that the explosion of gunpowder, so that night vision, infrared or laser measuring from the instrument, such as optical equipment failure. 2.The  cell phone jammer  company has also promised you stable, splendid and leading product and service. Strategic laser weapons strategic laser weapons to attack thousands of miles away ICBMs; to attack satellites in space and communications satellites. the color is good 2 good 3 coherent, directional good 4, brightness, high school, the frequency of the laser line width can not be a single frequency, a frequency, but always have a certain width of the spectral line width of the definition of υ υ maximum intensity for the spectral lines corresponding to half the difference between two frequencies (1) the natural line width: the natural line width: the width of atomic time and frequency atomic light emitting time t and width of the frequency υ satisfy the relation = 1 / υ = 1 / t ideal monochromatic light: the ideal monochromatic frequency width: width of the frequency υ → 0, which requires t  at any frequency of light is impossible is impossible, any frequency of light is impossible. It is said that this type of  cell phone jammer  has the best hand feel.The total width of the frequency of a certain width of the frequency set υ, the corresponding spectral line width is called the natural linewidth. λ is called the natural line width (2) Doppler width: the size of atomic velocity, Doppler width can be: atomic The size of the velocity to a value between zero and changes to a value between zero and changes so will the frequency υ values in the vicinity of light, causing a change in value, near the light frequency υ0 value, causing a changes in value, that caused a line broadening within a certain range, that caused a line broadening within a certain range, the width is called the Doppler width and this width is called the Doppler width.It is said that this type of  cell phone jammer  has the best control performance. Second, the laser monochrome (1) gas discharge tube light emission, for various reasons there is a gas discharge tube light emission, a spectral width of a spectral line width υ, then the light is not monochromatic cavity screening mechanism: (2) the screening mechanism of the cavity: the cavity length l set wavelength is λ set resonator length l, the wavelength is λ, the interference conditions for the 2l = jλ optical resonant cavity light with multi- resonance frequency of the light only to meet the resonance condition, and only the light in order to meet the resonance condition exists, the other light waves destructive interference occurs.
