green laser pointer  will be introduced in details in the following.
Therefore, it can detect extremely weak light signals, and convert it into a corresponding electrical signal. Common laser ranging sensors, which record and process issued from the light pulse to return to the time to receive the experience, you can Determination of target distance. Laser sensors must be extremely accurate determination of transmission time, because the speed of light is too fast. Based on consideration of the overall layout, the design uses 16 of the laser head and seven receiver to take "one" shaped arrangement of the way, two-row arrangement, each row of eight, two adjacent laser emission tube interval of 18cm. In order to facilitate the receiving road is reflected back into the laser infrared receiver tube, the installation when the launch tube and receiving tube to each other there is an inclination in order to better receive the signal.  This means that God means that God trillionth of 36 seconds ultrashort moment within the light II in 1000 trillionth of a second ultra-short moment. If the supply management of  green laser pointer  is permitted.
Burst out within a trillionth of a second is equivalent to a global grid of ultra-short moment, power generation, the strong power of several ten times. Generating several ten times more powerful power. Extreme physical conditions in nature only in the nuclear explosion center, the stellar interior and the edge of the universe, black holes can exist. Ray machines, light optical Key Laboratory of scientific and technical personnel repeatedly refresh these two indicators, to create again and again "faster and stronger," the miracle in less than 10 square meters on the optical bench. April 13, 2006, 9 SG Ⅱ device added a new laser output energy to break the record, compared with the previous 5.8-fold, 9-way beam-diameter, 8-way beam 190 mm to 310 mm. 
Particle transition to the high energy level on the low energy level E1 of this process called stimulated emission. The characteristics of stimulated emission itself is not a spontaneous transition, but by the stimuli of external photons. Thus exactly the same as the frequency of the particles released from the photon with the original photon direction of propagation, phase and polarization, can not distinguish which one is the original photon, which is generated by the excitation photons by stimulated emission of radiation due to optical radiation is proportional to the energy and photon number of cases, therefore, stimulated emission, optical double the radiation energy increases. Wave point of view, set the external photon is a wave by stimulated emission of photons for another wave, due to the phase of two waves, vibration direction, the direction of propagation and the same frequency. The material of  green laser pointer  is being purchased.
