Laser is defined as a special photon produced by extra-nuclear electrons at photons with high brightness, high monochromaticity, and high correlation, in the forward reference to laser generation and characterization for laser generation, 01. Laser working material means substances capable of producing lasers, usually a transparent medium with high purity, density and evenness. Laser leaps to laser leaps mean that when an atomic extranuclear electrons leaps from a high-energy to a low-energy level, they release a photon, which in turn triggers other atomic extra-nuclear electrons leaps, creates a chain reaction and eventually produces a laser. Laser basic knowledge gas laser is one of the most common lasers whose working material is gas or vapour, stimulating atomic extranuclear electrons, such as discharge or combustion, and producing lasers. Gas laser liquid lasers use liquid as a working substance to stimulate atomic extra-nuclear electrons, such as pumps or electric fields, to produce lasers. Liquid laser solid lasers use solids as work material, stimulating atomic extra-nuclear electrons, such as heat or light stimulation, to produce lasers. A solid laser laser generation method optical amplifier is a device used to magnify lasers by increasing their energy and power to increase their brightness or penetration. Optical amplifier fibre-optic amplifiers are a device used to magnify lasers and to increase the transmission efficiency and output power of lasers by increasing their energy and power when transmitting lasers in fibre-optics. Fibre-fibre amplifier laser magnification technique 02 laser characteristic lasers have very small dispersing angles and are almost an ideal set of parallel light with long distances of transmission. The laser has a single wavelength, a pure frequency height and a pure colour. Since the laser launch is a light, it is very relevant. The brightness of the laser is very high and can be tens or even hundreds of times greater than the brightness of the sun. The characterization of directional monochrome, which is relevant to each other, has high brightness lasers and directly uses telecommunications to control the strength of the lasers, thus achieving a modem. Modifiers for lasers, such as the use of acoustic, electric, etc. The laser mode of modem indirectly regulates the adc information processing directly using the relevant characteristics of the laser and allows for high accuracy and speed. Communications can achieve long-range, high-speed and high-capacity communications using the characteristics of high laser brightness, directional orientation and monochrome. High precision measurements, such as laser ranging, laser interferometry, etc., can be achieved by measuring the relevant properties of lasers.
