A fiber laser (or fibre laser in Commonwealth English) is a laser in which the active gain medium is an optical fiber doped with rare-earth elements such as erbium, ytterbium, neodymium, dysprosium, praseodymium, thulium and holmium. They are related to doped fiber amplifiers, which provide light amplification without lasing.
A test target bursts into flame upon irradiation by a continuous-wave kilowatt-level carbon-dioxide laser. The carbon-dioxide laser (CO 2 laser) was one of the earliest gas lasers to be developed. It was invented by Kumar Patel of Bell Labs in 1964 [1] and is still one of the most useful types of laser.
It is published by Wiley-VCH and contains reviews and original papers/letters. The journal was established in 2007 by the founding editor-in-chief Theodor W. Hänsch (Ludwig Maximilian University of Munich). Originally, the journal only published review articles. Since 2012, it also contains original papers and letters.
The first in-fiber Bragg grating was demonstrated by Ken Hill in 1978. [2] Initially, the gratings were fabricated using a visible laser propagating along the fiber core. In 1989, Gerald Meltz and colleagues demonstrated the much more flexible transverse holographic inscription technique where the laser illumination came from the side of the fiber.
Laser welding of polymers is a set of methods used to join polymeric components through the use of a laser. It can be performed using CO 2 lasers, Nd:YAG lasers, Diode lasers and Fiber lasers. [1] When a laser encounters the surface of plastics, it can be reflected, absorbed or penetrate through the thickness of a component.
[5] [non-primary source needed] However, laser-based free-space optics lost market momentum when the installation of optical fiber networks for civilian uses was at its peak. [citation needed] Many simple and inexpensive consumer remote controls use low-speed communication using infrared (IR) light. This is known as consumer IR technologies.
