coherent beam amplifier的意思|示意

Coherent beam amplifiers are a type of laser amplifiers that use a single laser beam to amplify the power of a different laser beam. The input beam, typically provided by an injection laser, is amplified by the output beam of the same laser. The process is known as stimulated emission, as the input beam stimulates the emission of photons from the output beam.

The output beam of the coherent beam amplifier is significantly more powerful than the input beam, resulting in an amplification of the signal. This makes the coherent beam amplifier useful for a variety of applications, including laser welding and laser cutting. In laser welding, a coherent beam amplifier is used to increase the power of the laser beam so that it is strong enough to cut through the material to be welded. This process is much faster than conventional welding, as the laser beam is able to penetrate the material much more quickly.

In laser cutting, the coherent beam amplifier is used to focus the laser beam to a small size. This allows the laser to cut with greater precision and accuracy than with a standard beam of light. The coherent beam amplifier is also used in other applications such as spectroscopy and materials processing.

Coherent beam amplifiers are relatively simple devices, and can be easily bought from a variety of sources. They are also fairly inexpensive, making them a popular choice for many laser applications.
