Optics light and lasers
WebOptics and Photonics. Optics and photonics is primarily about the science of light, its generation and manipulation, and its interaction with gases, plasmas, molecules, and solids, including micro- and nanostructures. It is a highly interdisciplinary field, bringing together researchers from physics, electrical engineering, chemical and ... WebJun 1, 2024 · Structured light from lasers Structured light can also be created directly at the source, in so-called structured-light lasers. Researchers creating structured light from cavities in the early lasers used intracavity wires, stops and apertures to produce Hermite-Gaussian and Laguerre-Gaussian beams.

WebOct 10, 2024 · The pioneering work on both masers and lasers was recognized in 1964 with the award of the Nobel Prize to Charles Townes, Nicolay Basov, and Aleksandr Prokhorov “for fundamental work in the field of quantum electronics, which has led to the construction of oscillators and amplifiers based on the maser-laser principle.”. WebSep 12, 2024 · A laser is device that emits coherent and monochromatic light. The light is coherent if photons that compose the light are in-phase, and monochromatic if the photons have a single frequency (color). When a gas in the laser absorbs radiation, electrons are elevated to different energy levels.
