A telescope in the Very Large Telescope system producing four orange laser guide stars. A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The word laser is an anacronym that originated as an acronym for light amplification by stimulated emission of ...
The Peresvet ( Russian: Пересвет ), named after Alexander Peresvet, is a Russian laser weapon for air defense and anti-satellite warfare. [4] [3] [5] The Peresvet is one of the six new Russian strategic weapons unveiled by Russian President Vladimir Putin on 1 March 2018. As of May 2022, five units of the system are claimed to be in ...
Laser Interconnect and Networking Communications System (LINCS) is a test of laser communication in space using two cubesats launched in June 2021. Background [ edit ] It was built by General Atomics for the US DOD 's Space Development Agency .

A laser weapon [2] is a type of directed-energy weapon that uses lasers to inflict damage. Whether they will be deployed as practical, high-performance military weapons remains to be seen. [3] [4] One of the major issues with laser weapons is atmospheric thermal blooming, which is still largely unsolved.
Laser-ultrasonics uses lasers to generate and detect ultrasonic waves. [1] It is a non-contact technique used to measure materials thickness, detect flaws and carry out materials characterization. The basic components of a laser-ultrasonic system are a generation laser, a detection laser and a detector.
Amblyopia. Anisometropia is a condition in which a person's eyes have substantially differing refractive power. [1] Generally, a difference in power of one diopter (1D) is the threshold for diagnosis of the condition . [2] [3] Patients may have up to 3D of anisometropia before the condition becomes clinically significant due to headache, eye ...
Deep Space Optical Communications Demonstration. Deep Space Optical Communications ( DSOC) is a laser space communication system in operation that improved communications performance 10 to 100 times over radio frequency technology without incurring increases in mass, volume or power. [1] DSOC is capable of providing high bandwidth downlinks ...
