What's the difference with ordinary light

The new type of  cell phone jammer  is made of aerometal, which is firm and durable.Thermal cracks. Hardness / HV HV distance from surface / mm layer of carbon + alloy eutectic alloy layer ledeburite for the carbide eutectic ledeburite ledeburite distributed a large number of dispersed carbide particles and the substrate alloy heat-affected zone District 4 laser cladding 4 laser cladding in a different way of packing surface to be coated in advance to put the selection of coating material, by laser irradiation of different ways of packing surface to be coated in the coating pre-placement options materials, and thin while the substrate surface melting and rapid solidification to form a very low dilution, and thin while the substrate surface melting and rapid solidification to form a very low dilution, and the substrate material to form a metallurgical bond of the surface coating to significantly improve the surface of the matrix material wear and corrosion, heat, metallurgical bonding of the coating, thus significantly improving the surface of the matrix material wear and corrosion, heat, oxidation, and other physical characteristics of a process . And other physical characteristics of a process.This new  cell phone jammer  contains the child safety lock, which cut the power when it doesn’t work.
Laser cladding for easy to wear, impact, erosion, laser cladding for easy to wear, impact, erosion, oxidation corrosion performance of the local parts require special preparation of the surface coating.The  cell phone jammer  is a class A laser module.Describes the mechanism of laser-based laser to produce a history of laser applications, laser type Page 1 of laser generation mechanism of a laser-produced laser mechanism Page 2 1 mechanism of laser-produced four basic issues: the four basic questions.The  cell phone jammer  is with interference free wireless frequency band
What is Laser? 2. Laser What's the difference with ordinary light? 3 Why are there these differences? 4 how to generate the laser? Page 3 1. What is a Laser? Laser Light Amplification by Stimulated Emission of Radiation "light amplification by stimulated emission of radiation", "laser" in 1964, naming the mainland; laser "," laser "Hong Kong, Taiwan, laser," Laser in the 20th century following the Atomic Energy computer, semiconductor atomic energy, computer semiconductors, the human computer laser Atomic Energy, another major invention of the semiconductor.The V-309  cell phone jammer  is exclusively designed for computers and multimedia PPT demonstration.

Laser (1) Laser color is good; (1) Laser color is good; a good monochrome laser monochrome best krypton lamp Kr86? Λ = 4.7 × 10-3 nm frequency stabilized He-Ne laser? λ = 1.0 × 10-9 nm ordinary light Page 5 2. What's the difference of laser light with the ordinary? What's the difference with ordinary laser light? (2) the direction of the laser is good; (2) the direction of the laser is good; laser laser beam laser shines a good direction to 38 million km of the moon, the spot diameter is only ~ 2km ordinary light flashlight shines light ~ m office, expanded into a great spot.The outer shell of  cell phone jammer  applies high-level PVC material but not metal.
