The operation mode of green laser pointer is very simple

green laser pointer can also be used as lights dispersing in all directions.
Analysis: static and dynamic than the calculation by the join of the polarizer and the Q-switch crystal, measuring the value of the static energy than dynamic energy. It can be seen from the above

data, the movement will be reduced with the increase of input energy. That, dynamic laser pulses in the high energy input (Q modulation pulse) is the peak power is increased, but the pulse energy

decreases. Passive saturable absorber Q-principle: the passively Q is the use of of passively crystal saturable absorber. Material becomes transparent as the energy density increases up. The energy

density reaches a certain high-value, the material will be "saturated" or "bleaching", which leads to produce a high transmission rate. The operation mode of green laser pointer is very simple.
The specific parameters and performance of green laser pointer has been described
Can saturable absorber in the bleaching process is based on the saturation of the spectral transition. If the laser wavelength will be a high absorption rate of the materials installed in the laser

cavity, it will prevent laser oscillation at the beginning. As the gain increases in the pump pulse duration and more than round-trip loss, the cavity of the luminous flux will increase sharply,

resulting in passive Q-switch is saturated. Under these conditions, the loss is at the end in order to establish the Q-switched pulse. Turn the power off, remove the electro-optic crystal (Note Do

not pull the crystal connection). Users just need to gently press the buttons on green laser pointer and release the buttons if not necessary.
The tetravalent chromium ion doped crystal inserted the location of the electro-optic crystal. Adjust the optical path, so that collimated light is exactly through the center of the crystal. Open

point power to the spot, then use photo paper, increasing the voltage of the injection of the xenon lamp, and observe the changes in the spot. Received pulse probe laser to observe the waveform to

change the injected voltage, and then observe, compare the two waveforms. First adjust the dynamic laser until the spot round the steps mentioned earlier. After which can be used as the back of the

paper to accept dynamic laser did not find the strengths, the nonlinear crystal can be installed (to prevent damage frequency doubling crystal under high power).The Pockels box for pressurized tune Q. Figure 2.6
