Light Detector - an overview | ScienceDirect Topics- laser light amplification properties of materials ,Typically, a light emitting diode (LED), rather than a more expensive laser, is used as the light source. LEDs emit more than one wavelength of light; a laser emits a single wavelength. The product of wavelength, λ, and optical frequency, v, is the speed of light in a vacuum, which equals 3×10 8 m/s.

The term "laser" originated as an acronym for "light amplification by stimulated emission of radiation". A laser differs from other sources of light in that it emits light coherently. Spatial coherence allows a laser to be focused to a tight spot, enabling applications such as laser cutting and lithography.
For the M 2 measurements, the same 1,064 nm laser diode and coupling setup as described above was used to launch light into the 1-km-long NANF (the input power was ~15 mW). At the NANF output, a ...
Single crystals of BaTiO3 exhibit small switching fields and energies, but thin-film performance is considerably worse, thus precluding their use in next-generation devices. Here, we demonstrate ...
Ytterbium-doped laser crystals and glasses have a number of interesting properties, which differ from those of, e.g., neodymium-doped laser gain media:. They have a very simple electronic level structure, with only one excited state manifold (2 F 5/2) within reach from the ground-state manifold (2 F 7/2) with near-infrared or visible photons.

A semiconductor laser that is used for signal transmission in optical fibre is the laser diode, where LASER stands for Light Amplification by Stimulated Emission of Radiation. A laser diode is like a light-emitting diode that emits a high-powered light through a glass lens to reduce signal loss. A laser diode is also called an injection laser ...

A commercial laser for cutting materials uses a motion control system to follow a CNC or G-code of the pattern to be cut onto the material. The focused laser beam is directed at the material, which then either melts, burns, vaporizes away, or is blown away by a jet of gas, leaving an edge with a high-quality surface finish.
Single crystals of BaTiO3 exhibit small switching fields and energies, but thin-film performance is considerably worse, thus precluding their use in next-generation devices. Here, we demonstrate ...

The ultraviolet light from an excimer laser is well absorbed by biological matter and organic compounds. Rather than burning or cutting material, the excimer laser adds enough energy to disrupt the molecular bonds of the surface tissue, which effectively disintegrates into the air in a tightly controlled manner through ablation rather than ...
