Cell phone jammer can meet different needs

For example, an output power of 1mw of He-Ne laser with high brightness. For example, an output power of the laser output of laser, focused through the lens, its brighter than the sun's output of 100,000 high-brightness laser, focused through the lens, its brighter than the sun brighter times. Directional coherence of the laser field intensity is high - a stable standing wave field, perpendicular to the laser propagation direction of light called the transverse mode field distribution, usually about the quality of the beam, mainly the transverse mode output beam. Spatial shape of the laser beam by the spatial shape of the laser beam from the laser resonator is determined. Most of the laser output are higher order mode. Determined by the cavity. cell phone jammer can meet different needs.Most of the laser output are higher order mode. Impact on the processing of laser mode 1, the fundamental mode Gaussian beam, the advantages: a large diffraction loss, can reach the diffraction limit, so the fundamental mode beam divergence angle is small, the energy concentration. Advantages: large diffraction loss, can reach the diffraction limit, so the fundamental mode beam divergence angle is small, the energy concentration. Inadequate: the smallest in the cavity mode, power is not, and the uneven distribution of energy. Inadequate: the smallest in the cavity mode, power is not, and the uneven distribution of energy. Applications: laser cutting, punching, applications: laser cutting, drilling, welding, etc. 2, higher order mode, advantages: high output power, a more uniform energy distribution advantages: high output power, less: less: divergence powerful applications: laser hardening.The protection range ofcell phone jammer is 10-30m. Application: Laser hardening, metal surface treatment 3, uniform optical systems, reflective mirror focus points is to use a large area of broadband high-power laser surface cladding and heat treatment of the essential components of broadband, both with excellent light effects. Divergence and alignment system 4, the divergence and intensity distribution, when Z = 0 时, θ = 0 (that is, at the waist, divergence angle of a plane wave) (ie, at the waist, divergence angle of a plane wave) region is defined as 1.1.2 The laser beam collimated beam brightness area brightness light-emitting surface is to describe the characteristics of a physical quantity, source brightness light-emitting surface brightness is to describe the characteristics of a physical quantity, light intensity (B) is defined as the solid angle per unit area The radiated power (P). The protection range of cell phone jammer  is adjustable.The light source brightness: solid angle per unit area on the radiated power. The light source brightness: PB = 2 2 2 π Aθ is: For nearly diffraction limited beam, laser beam focusing properties of a laser beam focus in the form, the transmission type: commonly used in the following 2KW laser beam laser system 1.1.3 the focusing properties of spherical reflective: kW or more for high-power laser beam focusing properties 1.1.3 2, focal spot size and depth of focus, (1) the actual focus lens spherical lens used to focus the laser beam spot size from the smallest can be approximately represented as determined by the diffraction spots waist radius and the minimum determined by the lens aberration diffuse plaques and the minimum spot size radius of which: minimum focus spot size and focal length of the corresponding: to get a small focused spot diameter of the smaller wavelength better, the lower the better order of transverse modes (b small), the k value is smaller lens (with concave - convex mirror). The working mode of cell phone blocker is intensive and bidirectional frequency sweeping.
