The technical program of cell phone jammer will be discussed and determined finally

Said WDG-30 WDG-type grating monochromator is used to identify the laser wavelength. Wavelength accuracy of 1, with ground glass joints cut into the light, the joints can be directly observed eyepiece. Adjusted to make the resonator cavity axis and the capillary discharge tube axis is coincident, its deviation directly affect the size of the laser power. For this analysis, the adjustment of the cavity is decomposed into Parallelism deviation deviation deviation δ2 δ1 and vertical two parts. Symmetrical cavity, for example, mirrors M1, M2 center of curvature, and its connection to the cavity axis, the optical axis relative to the tube axis distance of r, assuming the maximum allowable deviation of rm for the capillary diameter D of 1 / 10, the available parallelism deviation δ1 M1 or M2 mirror deflection angle said. mirrors the larger radius of curvature R, the smaller the allowed deviation of parallelism, the higher the precision of adjustment. Figure 6 shows a schematic vertical δ2, mirrors M1, M2 center of curvature, respectively, located on both sides of the tube axis, displacement is r ', the new optical axis of the connection, then M1 and M2 are parallel to each other , only one optical axis angle with the tube axis, assuming that the capillary length equal to the cavity length L, the maximum allowable deviation of the optical axis on the lens with the rm said, we can see from the figure geometry. The quality feedback of cell phone jammer will be help the engineer with improving the quality of cell phone jammer .
Type shows that when the radius of curvature than the cavity mirrors grew up, allowing the vertical deviation larger than the parallel deviation. If the regulation mirrors a sense of volume (or accuracy) than to allow the vertical deviation is small, the laser when the laser transfer, you can also carefully adjusted so that the vertical deviation decreases, so that the laser power increased. Straight into the cavity does not mean cavity dispersion prism laser cavity (Figure 7 (a) below), adjust the light when you use something called the target adjustment tool. Light target structure is a plane with a mask at the handle, engraved in the middle of screen and a small cross-line lighting, cross the center line opened a hole diameter of about 0.8mm. Adjustment for engraved with laser crosshairs at one end of a face, so that the back of the eye from the light target observation through the hole in a discharged state of the capillary, the diaphragm can be seen in the mirror light on the background of a diameter of about 2 -3mm of the discharge capillary cross-section, the background color than the surrounding light. If the holes in the vicinity of the capillary axis, within the capillary cross-section should only see a brighter tip big bright spot, which is the axis of the capillary discharge. Figure 4.7 (b) below, up and down to adjust the position of the light target, the small bright spot in the center of the capillary cross-section, which is light in the target hole on the axis of the capillary. The technical program of cell phone jammer will be discussed and determined finally.
