Some data knowledge about Cell Phone Jammers
If microscopic particles such as atoms or molecules with high energy and low energy level E2 E1, E2 and E1 energy level populations on the number density of N2 and N1, in the two-level transition between the existence of spontaneous emission, stimulated emission and stimulated transitions absorption transition, three processes. The page-turning Cell Phone Jammers has been widely applied in society.Transitions generated by stimulated emission of light by stimulated emission, and the incident light has the same frequency, phase, propagation direction and polarization direction. Therefore, a large number of particles in the same excitation of coherent radiation field produced by the stimulated emission light is coherent. Stimulated emission transition probability and stimulated absorption transition probabilities are proportional to the incident monochromatic radiation field energy density. When the two-level statistical weights are equal, the probability of the two processes are equal. In the case of thermal equilibrium N2 <N1, so stimulated transitions dominate the absorption of light through the material is usually due to shock absorption and attenuation. All teachers can use Cell Phone Jammers to remove the embarrassment of being restricted by the dais.Excitation energy can damage the outside thermal equilibrium leaving the N2> N1, this state is called population inversion. In this case, the stimulated emission transition dominant. Light through a period of length l in the inversion state of the laser working substance (active substance), the light intensity increases eGl times. G is proportional to the (N2-N1) of the coefficient, called the gain factor, and its size is also working with the nature of the material and the laser light frequency.
        After 30 years of development, the laser is now almost ubiquitous, it has been used in life, all aspects of research: Cell Phone Jammers has been added anti-trembling function.Laser acupuncture, laser cutting, laser cutting, laser welding, laser hardening, laser discs, laser range finder, laser gyro instrument, vertical laser, the laser scalpel, laser bombs, laser radar, laser guns, laser guns, in the near future, the laser will certainly be more widely used.
Strategic laser weapons to attack thousands of miles away ICBMs; to attack satellites in space and communications satellites.
