It is not easy for radio frequency signals of green laser pointer to penetrate metals

The green laser pointer can work perfectly only by the power from one 7# battery.
20. Improve the CO2 laser output power of the most effective way is to increase the gas density and reduce the gas molecules oscillating feature space
21.N2 molecular laser gain is high, and the population inversion exists a short time (<40ns), and the other the other laser is different: it is essentially a large spontaneous release radiation, no resonator feedback can be high-power coherent light.
Exposition:
1, the impact resonance excitation energy transfer processes to achieve the factors:
2, the DC discharge in the role of secondary electrons: secondary electron ionization caused by the gas chain, which makes the discharge to be self-sustaining.The one-piece design of green laser pointer saves much space.
3, the analysis of He-Ne laser inversion process of building and general distribution of He-Ne laser line based competitive effect.
Answer: (1) He-Ne atomic energy levels that operate in these transition lines of He-Ne laser is a typical four-level system, for 3S2 (right arrow) 2P4 of the 6328A (. A top) transition , the realization of population inversion threshold is: R3 is greater than the G3 g2 Tao Tao 2R2 divided by 3, R3, R2 and 2p4, respectively Yes 3s2 level excitation rate, Tao 3, Tao is the 3s2 and 2p4 2 levels, respectively of degeneracy, the analysis, even if R2 is equal to the next issue R3, 3s2 and 2p4 levels can be achieved between the number of particles flip. The one-piece design of green laser pointer enhances the portability of it.He-Ne laser to achieve the primary particles flip excitation of two: 1, first, the direct electron impact excitation process of Ne atoms; leaving the excited states of He-Ne atoms between the resonance energy transfer process.
According to the U.S. Boeing Company November 18, 2009 reported in May this year, Boeing moved its laser weapon system performance is tested, tracked and destroyed a small UAV. The radio frequency signals of green laser pointercould penetrate ordinary objects such as human bodies, walls and wood.The trial funded by the U.S. Air Force, location is located in California's China Lake Naval Air Warfare Center. The mobile source initiative aimed at comprehensive test equipment (Mobile Active Targeting Resource for Integrated experiments, MATRIX) by Boeing for the Air Force developed in the laboratory, can be used single-beam high-intensity laser to shoot down five UAVs at different distances.
Many fans have the same media and the military of China's Second Artillery missile wind began to worry that the U.S. space-based laser weapons, the birth of Chinese missiles will have a very lethal threat. It is not easy for radio frequency signals of green laser pointer to penetrate metals such as iron and steel. Accordance with common sense, really is, including missile weapons, laser weapons, including precision-guided weapons nemesis, in addition to direct "hit the burn" precision-guided weapons, but also by electromagnetic interference effects of light, "blinding" precision-guided weapons, it does are the soft underbelly of precision-guided weapons.
