The wireless RF technology is used for laser pointer

In art galleries, laser pointer may be not suitable.
Laser show in the 1960s the concept of emergence, the world's scientists are trying to show the laser light source technology used in the study. Chinese Academy of Engineering Xu Zuyan first laser show in the country proposed the concept, and preliminary studies. But then the laser level of development constraints, the slow progress of research projects. In the 1990s, with the solid-state lasers successful development of key materials, which greatly promoted the study of laser display technology, laser display technology research in 2003 to obtain a historic breakthrough, by the success of RGB three primary colors mixed into white light visible lasers, and a series of engineering prototype.It is the brief introduction to the green ray laser pointer .
Therefore, we must grasp the characteristics of inhomogeneous broadening media, that is, different light-emitting particles only contribute to the corresponding part of spectral lines. Which lead to the expression of the gain coefficient and inversion - hole burning effect. Analysis can be: I make the uniform light-based media for widening waves of various frequencies decreased the gain coefficient are multiples of the same; and inhomogeneous broadening of the type of media it can cause a range of light decreased the gain coefficient, and drop multiple different. As the particles in the medium for the thermal motion disorder, particle velocity component along the cavity axis to meet the Maxwell velocity distribution law. Work in an inhomogeneous broadening due to the material in each specific type of particle, v only with a certain frequency of light interaction. Low and high-energy laser weapons, space weapons, and laser ranging. Laser components. By the laser pump source, the work material and the resonant cavity formed. Therefore, the ruby is still an excellent working material and widely used. The wireless RF technology is used for laser pointer .
Made with a large ruby single pulse output of the device has reached thousands of joules of energy. Q-switched single-stage device can easily be tens of megawatts of peak power output (using such devices have been successfully contained corner reflector satellite ranging experiments conducted). Multi-stage amplifier parts have reached thousands of megawatts of peak power output to 10,000 MW. Ruby laser is a contribution to the development of a relatively large crystals. This section focuses on the structure of He-Ne laser and the excitation mechanism, output characteristics, CO2 laser excitation of the structure and the structure of Ar + laser, Ar + laser operating support of.
