page-turning green laster pointer with bright laser light

This experimental setup used is shown in Figure 4. By a continuous or pulsed green laser output of laser beam through the filter is not filtering the LD laser crystals absorb light of 808nm pumped 1064nm through the output mirror of the fundamental frequency of light, the light through the sample used for spectroscopic When a small part of the 532nm laser light is reflected into the detector to detect the light intensity changes.How long does the 7# battery keep when it is used in green laster pointer? Detector output signal is input to the feedback controller is amplified and processed; feedback controller generates control signals are sent to the laser in the drive, the LD drive current control, thus changing the LD pumping power, the laser crystal gain changes, compensation green laser green laser output power fluctuations, so that the green laser output power to be stable. Figure 5 shows no optical feedback when the green laser output power versus time curve. One can see that in the free-running conditions, the green laser output power variation is relatively large. This large magnitude of changes of green lasers can not meet the stability requirements for a high number of laser applications. Figure 6 is for the direct control of the LD drive current of the optical feedback of the green laser output power versus time curve.
To our knowledge, this laser’s performance in its class is the best. (2) solid-state green laser pulse in order to get high peak power, this paper developed using acousto-optic Q-switch pulsed green laser intracavity frequency doubling. Figure 2 is a block diagram of it. Comparatively speaking, light of green green laster pointer is brighter than the red one.The acousto-optic Q components used green lasers and green laser is basically the same row, only Nd: YVO4 crystal end pumped spherical radius of curvature is 100mm, the other in the frequency-doubling crystal inserted between the output mirror and acousto-optic Q switch, the ultrasonic frequency of 70MHz, the direction of light through the length of 18mm, two-pass smooth coated for 1064nm and 532nm while the high transmittance of the antireflective coating, each surface of the residual reflectivity <0.25%. In order to improve the stability of device performance, while easy to adjust the laser, the pumping LD, coolers, focusing system and the laser crystal with epoxy resin as a whole, and then fixed in a large heat sink base. If you need a page-turning green laster pointer with bright laser light, please choose the green green laster pointer. The frequency-doubling crystal, and acousto-optic Q-switch were used to adjust the output mirror frame fixed to the radiator, their position and orientation can be adjusted. The output optical parameters of measuring instruments in addition to the aforementioned continuous green laser parameters measuring instruments used, the same flight with the Chongqing Wei Photoelectric Technology Co., Ltd. GT101 silicon photodetector detects the green laser pulse, with Agilent’s 54622A 100MHz Oscilloscope type measurement of laser pulse width.
