Lens 50% reflective film coated, only part of the laser through the substrate, the surface coating layer of the substrate than the absorption dominates the absorption, GaAs than ZnSe, as shown in Figure 2. GaAs lasers commonly used operand kW output mirror. 99% reflective lens coating film, the transmitted light is only 1%, the absorption of light transmissive material is very small, not only the quality factor of GaAs high heat distortion. Ge also because of its good thermal conductivity and high heat distortion of the quality factor, close to the GaSe level, as shown in Figure 3. Laser beam quality factor M 1.1.5 M2 beam quality factor of the laser beam output characteristics of the laser beam quality is an important indicator parameters.The intelligent management system of cell phone jammer can perform function of safety and protection. Evaluation of beam quality in many ways, has used the focused spot size, the far-field emission angle as evaluation criteria, advantages and disadvantages of these evaluation criteria, evaluation of the laser beam to form a long time were not of uniform quality standards. In 1988, the use of dimensionless quantity - M2 beam quality factor of a more scientific and reasonable description of the laser beam quality, and adopted by the International Standards Organization. The actual width of the beam waist and far-field divergence angle of the product 1, define: M = base width of Gaussian beam waist and far-field divergence angle of the product 2 for the fundamental mode (TEM00) Gaussian beam, with M2 = 1, the beam good quality, the actual beam M2 are greater than 1, characterized by a multiple of the actual diffraction-limited beam characterized by a multiple of the actual beam diffraction limit. cell phone jammercan make sure that environment can be purified and secrecy leaking and crimes can be prevented.Characterization of the actual beam quality due to multiple sub-diffraction-limited beam M2 can be expressed as πD0θ M = 4λ 2 1.2 laser interaction with solid materials 1, the laser and the role of the general rules of A material change in energy processes: laser incident surface, a were reflected, a part of the Division into the timber interior. Of opaque material, transmitted light is absorbed. The rate of absorption or radiation α = 1? RZ at the laser power density: Fv (z) = Fv0 (1? Rλ)? E? Αz B state change: the power density in different conditions, the surface area occurs a variety of changes.The intelligent management system of mobile phone jammer is the necessary outcome of humanized management. Such changes include temperature, melting, vaporization, the formation of holes and plasma cloud, etc.
