Laser protective glasses tell you please pay attention to laser

   Laser is a kind of light which does notexist in nature, and is characterized by good directivity, high brightness,good monochromatic and good coherence. Laser protective glasses manufacturersto tell you that the motion state of any kind of light emitting material withinternal particles, the laser more no exception. Facing this day our laseraspects are covered by some, but we found that the lack of laser protectiveglasses of fundamental laser laser will know why popular? What use lasercharacteristics? Laser is regarded as a peculiar light, because it has fourcharacteristics: general light completely with the.

   1 - directional light source (sun,incandescent or fluorescent lamps to light and light) from all sides, thedirection of the laser can be limited in less than a few mrad solid angle,which makes the shine on the direction of illumination increased thousands oftimes. Laser collimation, orientation and ranging is the use of gooddirectivity.

   2 high brightness laser is the brightestlight in this world, as long as the moment of intense light bomb blasting canbe compared with it. The sun light is about 103 (2 w / cm, and the sphericaldegree) output brightness of a high-power laser by sun light up 7 to 14 ordersof magnitude. So, although the total energy of the laser is not necessarilygreat, but because of high energy gathered easily in a micro dot occurs at highpressure and even tens of thousands of millions of degrees Celsius degreescelsius. Laser drilling, cutting, welding and laser surgery are using thischaracteristic.

   3 monochromatic good -- just anelectromagnetic wave. The color of light depends on its wavelength. Generallight source declared light generally contains a variety of wavelengths, is amixture of various color light. Sunlight contains red, yellow, green, green,blue, purple seven colors of visible light and infrared light, ultravioletlight and other invisible light. While a laser wavelength, only assembled inthe very narrow wavelength or frequency range. If He Ne laser has a wavelengthof 632.8 nm, its wavelength changes less than the size of 1/10000 nm. Becauseof the monochromatic nature of the laser, it provides a very favorable techniquefor measuring the density of the instrument and encouraging some scientificexperiments such as chemical reaction.

   4 - is a good coherence and shake scenefeatures. According to the characteristics of high directivity and highmonochromatic, the laser has excellent coherence. This characteristic of lasermakes holography become reality.

   Foreign direct photon effect from highlevel to low level during the transition of the remaining energy to emit photonmode (stimulated radiation), was released and the photon photon is foreign infrequency, phase, transmission directions completely consistent, which meansthat the external light to strengthen, we say to expand the light.Significantly, if after the stimulated absorption, so that in the high level thenumber of particles than in the low level (more particle number, rotation) ofthis kind of light is expanding the scene significantly, then there may be theformation of laser, is also the origin of laser.
