Filamentation of ultra-short laser pulse propagation in non-linear media offers significant potentials allowing to address numerous problems in military and commercial sectors. However, practical implementation of this requires an ability to control the USLP at its propagation through inhomogeneous media, like turbulent atmosphere. On the basis of our approach for combating turbulence effects on p ...

Ultra-short pulse lasers have advantages over continuous-wave lasers for directed-energy applications due to the high peak powers that can be reached. Directed-energy weapons are profoundly limited by the aberrations caused by atmospheric turbulence and current adaptive optics can correct for these aberrations only when the propagation medium is reciprocal. Unfortunately, nonlinear effects in the ...

The Department of the Navy has a need for the development of an additive manufacturing (AM) process for key vacuum electronic device components to meet on-demand, flexible, and affordable manufacturing requirements. The developed manufacturing method has a potential to reduce cost of vacuum electronics by as much as 70% as well as simplify and hence expedite production process of these devices by ...

A need exists for new weapon types that can rapidly strike targets around the globe within minutes. One current focus is the development of hypersonic strike weapons. Hypersonic weapons will have increased effectiveness, decreased time to target, and increased range. However, hypersonic projectiles will experience significant aerothermic heating necessitating thermal protection. This key techn ...

To be effective, modern military command and control requires an enormous amount of communication, coordination, and collaboration among the various forces, services, and coalition partners involved. Many tools have been developed or adopted from industry to meet this need; however, these same tools have significant limitations, the most important being that none of the technologies are Òaware of ...

This proposal describes an all optical fixed wing landing system for a aircraft carrier capable of flying an aircraft all the way to landing in a RF denied environment. The precision, reliability and accuracy of this system will allow control the aircraft without the help from the pilot all the way to touch down. It will work seamlessly with UAVs and manned aircraft that have been retrofitted with ...

SA Photonics has developed a concept for our Multiple Optical Beam Landing System (MOBLS) to provide autonomous landing of aircraft in RF denied environments. MOBLS utilizes multiple, redundant methods to determine the real-time location and bearing of the aircraft relative to the carrier-based landing strip. By having built in redundant modalities, MOBLS provides highly reliable landing informati ...

The purpose of this project is to demonstrate the feasibility of using an innovative, durable, low friction, and non-toxic solid lubricant coating for foil air bearings for air cycle machines (ACM). Acrees coating provides superior wear characteristics at all temperatures and provides a substantial improvement over polyimide type coatings that are currently used on ACMs. The coating consists of tw ...

Terrorist use of radioactive nuclear materials via nuclear and/or radiological dispersion devices (dirty bombs) is a serious threat. Therefore, it is critical to detect the proliferation of nuclear material. Critical challenges facing this objective include: (a) high sensitivity detection of signature emissions (e.g., gamma rays) from common radioactive isotopes behind shielding, and (b) cost-effe ...

A novel technique for achieving SSB-SC is proposed for achieving high dynamic range in analog applications. The technique employs an intracavity modulator together with an intracavity filter that blocks the modulation sidebands from being re-circulated. Spurious-free dynamic ranges (SFDR) exceeding 120 dB/Hz2/3 is achieved using this novel technique. Development of a prototype photonics circuit ...
