Laser technology is a high and new technology developed in the early 1960 s. The emission ability of the laser is strong and the energy is highly concentrated, which is hundreds of millions of times brighter than the ordinary light source and tens of billions times brighter than the sun's surface. If a medium-intensity laser beam is converged, a high temperature of thousands to tens of thousands of degrees can be produced in the focus. In addition, the monochromaticity of laser is very good. We know that different colors of light are determined by different wavelengths of light, while the wavelength of the laser is basically the same, the spectral line width is very narrow and the color is very pure. Because of this characteristic, laser is widely used in communication technology.
