We all know that most people in the career of laser, how many may understand some laser knowledge, so the use is much above the laser, laser using themost common Internet information is transmitted by optical fiber communicationisto take a lot of time, the laser we are strange, tasteless. But it is notour laser to see, but again there, wearing Laser safety glasses can timely prevent invalid laser aspersions on the eyes. And yesterday we Laser safety glasses to tell you about the high purity of the laser color.
The color of light is decided by the span (or efficiency) of the light. Have certain colors corresponding to the span. The radiation from the visible section of the span between about 0.76 decimillimeter scale spread to 0.4 decimillimeter, corresponding to the color from white to purple 7 colors,so the moon light on color. The single color light source as monochromaticlight source, its emission band span range. For example, helium lamp, neon, krypton lamp hydrogen lamp are only a monochromatic light source, a light emittingcolor. The band is wide span monochromatic light source, but there is stillacertain size distribution. The narrower the span of the light radiation, the better the monochromatic property. The input laser light scatter scale very narrow span, and very pure color. To enter the red He Ne laser asan example, the light scatter scale can narrow span to 2 * 10^-9 nm, is krypton lamp red emission with long spreading scale 2/10000. Thus, the monochromatic laser is far better than any kind of monochromatic light.
The laser to us Marvel actually not only that, not only is the automatic laser monochromatic light let us marvel, and pure good and can be controlled at any time, we can do a lot of things by using laser support.
