Overview of the laser amplifier constant good laser amplifier and laser (oscillation) is based on the same physical processes (light amplification by stimulated emission of radiation) laser cutting machine, the main difference to the laser amplifier (traveling wave) is not resonant cavity. The working substance in the optical pumping action, in population inversion wood laser cutting machine, when the light pulse from a laser (oscillation) generated by it, since the incident light frequency and amplification spectrum coincides with the gain medium, so excited particle state on a strong stimulated emission under the action of external optical signal. This radiation is superimposed on the external optical signal is amplified, so that the amplifier can output a bunch of much higher than the original laser beam emitted brightness. Laser amplifier must have a sufficient number of working substance inversion to ensure that the optical pulse signal when it is obtained by the gain due to various losses in sub-quality interior. In order to obtain a resonance amplification, requires amplifying medium has to match with the input signal level structure. History of laser constant good laser to new and old customers explain in detail the history of the laser 40 years or so since the invention of the laser cloth laser cutting machine, following the ruby ??laser as the representative of solid-state lasers, gas lasers, chemical lasers, dye lasers, atom lasers, ion lasers, semiconductor lasers, X-rays and fiber lasers have been brought forth. Various properties of lasers, such as frequency stabilized laser, stable laser power, polarization maintaining lasers, high-power lasers, steady direction ultrashort pulse laser and the laser is developed to meet different needs. Many areas of application of the laser after increasing variety of new products on display. Such as a laser interferometer, a laser rangefinder, laser medical equipment, laser drilling machines, laser light tank machines, laser heat treatment equipment, laser anti-counterfeit trademarks, laser communication systems, optical disk storage, so that the laser-guided weapons, and so on. Especially in the development of semiconductor laser as the light source universal communication system showing a strong vitality of the laser.
