The multiple functions of cell phone jammer can show the high economical efficiency

The pattern matching is to maximize this overlap. Improve the degree of overlap of the pump and oscillation light output laser beam quality, reduce the power of the pump diaphragm value, increasing the output power and slope efficiency of a very important role. Containing the cavity design of the thermal lens. By our theoretical analysis, the design of the cavity, we are the most important is to solve the problem of the thermal lens effect and pattern matching, so we want to design a heat stable cavity, that is the case of changes in the thermal focal length (pump power) not sensitive to the laser oscillation of the crystal at the light spot radius changes of the equivalent thermal lens focal length f of the laser crystal, so that the cavity is always in the stable area. When the customer selects cell phone jammer .
While maintaining good pattern matching and to ensure that all the cavity parameters within the scope of our request. Resonator design. As shown below for the resonant cavity structure diagram: structure diagram of Figure 2.1 cavity. Figure 2.1, Ml, M2 and M3 is the radius Rl, R2, R concave mirror M4 and the oc is the plane mirror. LO is the SESAM Ml distance L1 is the distance between the Ml and M2, L21 M2 to the distance of the laser crystal Nd: YV04 front-end, L22 laser crystal Nd: YV04 back-end distance of the M3, M4 for the plane mirror, So we can define the L3 is the distance between the M3 and the output mirror oc. When they decide to buy  cell phone jammer  for the practical and applicable use and operation.
514.5nm and 488nm is the strongest, accounting for 30% -40% of the total output power. Cavity coupled with a prism, after adjustment of the output available to single lines. Cavity plus the F-P etalon, the linewidth for the 3MHz a single frequency laser output. Output power and operating current. The discharge current is small, the output power is about and the current is proportional to the fourth power. Discharge current, the output power gradually becomes proportional to the square of the operating current. Output power and pressure. Discharge tube within the air pressure has a direct impact on the output power P, the experimentally measured was the discharge tube the best pressure and diameter d the following relationship. Or, the customer might have some advice about the design, technology or process of manufacturing  cell phone jammer .
China from the end of 1993 AIX200 low pressure MOCVD system for the development of QW devices, has developed dozens of InGaAsP series, the AlGaInAs series of materials and two series of strained QW material, the development of QW devices also achieved fruitful results. completed a number of "863" project has been the formation of the products have the following main devices: (1) General 1.3 m QW lasers, the first practical QW lasers began in 1995 for use in mobile communication optical fiber transmission repeater . Products of the strain the QW DFB lasers, the wavelength coverage of 1.5 ~ 1.57 m, the end of 1996, mass production and formally put on the market.
