The testing center of cell phone jammer has three floors

 The manager is companying the custom to visit the testing center of mobile phone jammer .
Semiconductor laser chip and the package is no longer along the Gong design and manufacture of traditional modes of production, increasing the chip's light output, the R & D is not limited to changes in the number of impurities within the materials, lattice defects and dislocations to improve internal efficiency, the same time, how improve the internal structure of the die and package, enhanced semiconductor laser photons emitted internally generated risk and improve light efficiency, to solve the heat, take the light and heat sink optimization, improved optical performance, speed up the process of surface mount technology SMD is the industry R & D mainstream direction. Semiconductor optoelectronic devices operating wavelength is and the production of semiconductor materials used in the device type associated. Semiconductor material exists conduction and valence band, conduction band electron can freely exercise the above, but below the valence band holes can allow freedom of movement, the conduction band and valence band are separated by a band, when the electronic absorption of light energy jump from the valence band to the conduction band to go, put the light energy into electricity, and with the power of electrons from the conduction band jump back to the valence band, but also the electrical energy into light, when the band gap materials determines the width of the working wavelength optoelectronic devices. Development of materials science so that we can use bandgap engineering of semiconductor materials can be cut with a variety of sophisticated, so that it can meet our needs and for us to do more things, but also make the work of semiconductor optoelectronic devices wavelength band gap materials breakthrough limit extended to a wider range. The testing center of cell phone jammer has three floors.
Laser cavity and the cavity can be divided into the external cavity. In the resonant cavity, the loss of many types of lasers, such as the deflection loss, there is a larger deflection cavity loss, and loss of confocal cavity deflection less suitable for low-power continuous laser output , but also such as inversion of the non-radiative transition losses (such losses can be classified as white noise), etc. and the like, are cavity long big loss.
