Laser structure

Laser structure
Although many types of lasers, but basically the same manufacturing principles, mostly composed of incentive systems, laser materials and optical oscillator cavity of three parts.
Excitation system is light, electricity, chemical energy generating device. Incentive systems to provide energy, laser materials in the most outer orbital electrons absorb energy to jump up atoms to create conditions for future release laser. Now there are incentives to use light, electricity, chemical reactions.
Laser substance is capable of generating a laser material. It has been found that thousands of such substances, such as ruby, neodymium glass, neon, nitrogen, carbon dioxide, metal vapor, semiconductors, organic dyes. The current physical state lasers by laser material points, there are four: the laser for laser material solid substance called solid-state lasers, gas lasers for laser material substance called gas lasers, semiconductor lasers for laser material called a semiconductor laser with a solution of an organic dye laser made called liquid lasers.
The role of the optical resonator is to strengthen the output of the laser brightness, adjustment and selected wavelength and direction of light.
