Laser original Chinese name called & other;
Laser & throughout;
、“
Leser & throughout;
, it is the English name of the LASER, is taken from the English Light Amplification by Stimulated Emission of Radiation of the abbreviation of the first letter of certain words.
Mean & other;
The light of the stimulated radiation amplification & throughout;
。
what be called & other; Stimulated radiation & throughout; ？ It is based on the great scientist Albert Einstein in 1916 put forward a new set of theory. This theory is said in the atoms that make up the material, have a different number of particles, Electronic) Distribution on the different level, on the high level of particles by a photon excitation, will be from high level to ( Transition) To the low level, at this time will radiate this light is the same and stimulate the nature of light, and in a certain state, can appear a weak light inspired a strong light. This is called & other; The light of the stimulated radiation amplification & throughout; , hereinafter referred to as the laser. There are mainly four characteristics: laser high brightness, high directivity and high monochromaticity, and high coherence.
laser high brightness: the brightness of the solid laser can be as high as 1011 w/cm2Sr. Not only that, after focusing laser beam by lens with high brightness, near the focal point is to thousands or even tens of thousands of degrees of high temperature, it is almost all of the materials can be processed make it possible.
high directivity of the laser: laser high directivity which can be delivered effectively in a long distance at the same time, also can get very high power density, ensure that focus on these two points are the important condition of laser processing
laser high monochromaticity, as a result of the laser high monochromaticity, so as to ensure the beam can accurately focus to focus on high power density.
high coherence: laser coherence is mainly describe the phase relationship of each part of the light wave. Singular characteristics of laser possesses as described above, therefore has been widely used in industrial processes.
