The technical report of cell phone jammers contains all technical parameters.
Predict the next 2-3 years, China's laser processing sales will rise by 3.5 billion yuan in 2008 to double, which means that will reach 70 billion yuan output value. All kinds of domestic manufacturing received laser processing technology, it will enable their products to increase the technical content, and accelerate product replacement, in order to adapt to the 21st century high-tech industries, to meet the needs of macro-and micro-manufacturing, research and development high-performance light source imperative. Extreme ultraviolet ultrashort pulse, ultra-high-power, high beam quality characteristics of the laser is currently being actively developed, in particular, is able to adapt to technical requirements of micro-fabrication laser light more a closely watched, and has formed an international competition. How to maximize the impact of the multimedia users’ body language with cell phone jammers .
The principle and characteristics of the laser processing. The principle of laser processing of the laser processing is a laser beam to the workpiece surface, removal of high-energy laser, melting the material and the change in surface properties. Laser processing is a non-contact machining, the tool will not work piece surface grinding directly observed resistance, so the speed of the laser processing, the processing object heated in a less and does not produce noise. The movement speed of the laser beam energy and beam can be adjusted so the laser processing can be applied to the different levels and scope.
Light waves while the feedback gain, so the monochromatic than the FP-LD. DFB-LD production technology development process, it was found directly in the active layer etching grating will introduce pollution and damage, so he proposed as shown in Figure 5-2 DFB-LD structure in Figure 5-2 DFB-LD structure diagram (3) good taking into account the reflectivity of the Bragg grating distributed Bragg reflector semiconductor laser, the grating placed on both sides or one side of the laser resonator, the gain region is not grating, the grating is only equivalent to a reflectivity changes with the wavelength of the reflection The mirror, which constitutes of DBR-LD. The technical program of cell phone jammers will be submitted to the manager for approval.
