Ultrafast Optics: Vector Cavity Lasers — Physics and Technology

Fiber lasers have found widespread applications in industrial material processing, scientific research and military systems due to their advantages of easy maintenance, excellent stability, compact size and low cost. One characteristic of fiber lasers, compared to other types of lasers, is that strong light is confined to propagating a long distance in a fiber core that has a very small cross-sectional area. This has the consequence that the nonlinear light interaction with the matter has a very long length. This results in the strength of all nonlinear optical processes being strongly amplified. This means that a conventionally weak, nonlinear optical effect can become significant. Therefore, apart from the practical applications, fiber lasers also constitute an ideal platform for the exploration of various complex nonlinear dynamics.

Integration of Adaptive Optics Into High-Energy Laser Modeling And Simulation

The U.S. Navy is constantly predicting future threats and contemplating new weapon technologies to counter them. One of those technologies is directed-energy (DE) weapons. Conventional weapons rely on the kinetic energy of projectiles. High-energy lasers (HELs), one type of directed-energy weapon, work in a fundamentally new way, using electromagnetic radiation to damage or destroy enemy assets.

Understanding Fiber Optic Transceiver Design and Test Rules

The design of avionics systems must balance several factors. First, engineers want to increase the performance of the systems installed in aircraft or spacecraft. Second, they want to reduce the size and weight of the equipment that must be carried. Third, they want to maximize the safety of the in-flight systems and maintain communication between the aircraft or spacecraft and other flight vessels and the command center, regardless of the circumstances.

Spatiotemporal Imaging Exploiting Structured Sparsity

Spatiotemporal imaging contains a large class of imaging problems, which involve collecting a sequence of data sets to resolve both the spatial and temporal (or spectral) distributions of some physics quantity. This capability is exploited in numerous different fields such as remote sensing, security surveillance systems, astronomical imaging, and biomedical imaging. One typical example is hyperspectral imaging, which is a powerful technology for remotely inferring the material properties of the objects in a scene of interest. Ultrasonic and thermal imaging are other important examples of spatiotemporal imaging where high spatial resolution is needed for urban planning, military planning, intelligence and disaster monitoring and evaluation.

Army Awards Combat Laser Weapon System Contract

The U.S. Army issued a contract award to accelerate the rapid prototyping and fielding of its first combat-capable laser weapon system. This prototype will deliver 50 kilowatt-class lasers on a platoon of four Stryker vehicles in Fiscal Year 2022, supporting the Maneuver-Short Range Air Defense (M-SHORAD) mission. The directed energy M-SHORAD capability is intended to protect maneuvering Brigade Combat Teams from unmanned aerial systems (UAS), rotary-wing aircraft, and rockets, artillery and mortar (RAM).
