There are many color choices for cell phone jammer
The cell phone jammer in the black color will be produced in the batch. Energy, computers, semiconductors, after another major human invention known as the "fastest knife," "the most accurate of the foot," "the brightest light" and "exotic laser," . The brightness of the sunlight it 50 million times. Its principle as early as 1916, the famous physicist Albert Einstein has been found, but until 1958 was only the first successful laser manufacturing. Laser is in a theoretical preparation and production practices in the context of the urgent need emerged, and it come out, you get extraordinary fast development, the development of not only the old laser optical science and optical technology gained a new life, and lead to the emergence of a new industry. Laser allows people to effectively use advanced methods and means unprecedented, unparalleled benefits and to get results, so as to promote the development of productivity. Laser is the substance produced by stimulated emission of radiation beam, laser welding is a high-energy laser beam welding heat source. Monochromatic laser with a good, directional, and high brightness. Laser line width of the narrow shape of the surface wave vibration does not change over time, have a good time and spatial coherence, the nature of the laser to the detection and communication has been widely applied. The user should use cell phone jammer according to the manipulating way of cell phone jammer .
Good direction means that the beam divergence angle small. Small divergence of the laser, the beam spot size is small, high power density, suitable for laser welding. High-quality laser output divergence angle of laser full-width is generally (1 ~ 3) × 10 ˉ 3 rad, deliberately carried away from the laser laser laser welding operation arrival. The high brightness laser show laser power density, which is required for laser welding material. Longitudinal mode laser mode and transverse mode of the points, commonly referred to as the mean transverse mode. Transverse resonant cavity light field on behalf of the lateral distribution of the (perpendicular to the light propagation direction), when an important laser parameters, has a great influence on the welding results. Transverse mode is usually TEMmn to said one representative of transverse electromagnetic TEM, m, n is perpendicular to the light propagation parallel to the surface x, y two directions transverse ordinal. M or n, ordinal judgments, it is customary to x, y direction in the valley on the energy distribution curves (nodes) to determine the number. m, n is generally a small positive integer, and sometimes call them Order. The using method of cell phone jammer is very easy normally.
