ABSTRACT: For this SBIR topic, we have proposed a novel high-power optical fiber pump combiner design that addresses the specific challenges associated with counter-pumping large-mode-area (LMA) double-clad gain fibers. Based on modeling and design optimization, we will fabricate kilowatt capable power combiner prototypes for pump coupling to double-clad Yb-doped polarization-maintaining (PM) fi ...

ABSTRACT: In response to the U.S. Air Force"s need for fiber cooling and pointing in high power fiber amplifiers of 1kW and up, i2C Solutions propose the development of a conformal thermal ground plane (TGP) technology to interface with heat sinks integrated into the active precision pointing fiber support structure. The result is a highly efficient thermal management solution, with respect to b ...

ABSTRACT: This proposal addresses an important need of DoD and MILSATCOM for satellite based receivers operating at Ka-Band having multiple beams (as many as 30) capability. Many of these beams need to be independently steered. This has traditionally been a major challenge because, as will be shown, the architectures that are required are very component intensive, which has made such antenna sys ...

Capco proposes using materials developed in previous SBIR obscurant research efforts to prepare UVCM devices for test and evaluation. UV absorption will be optimized through particle geometry and processing parameters.

TDA Research, Inc. (TDA) proposes new materials with exceptionally high absorbance in the ultraviolet that are designed to be used as obscurants to defeat the dual-band tracking systems used in modern missile systems. The Navy seeks advanced obscurant materials that will protect military assets such as aircraft from these modern missiles. TDA"s new nontoxic materials will be dispersible and tailor ...

ABSTRACT: The Etched Air Taper Combiner as fist proposed by the US Air Force Academy has the advantages in that the input fiber bundle, the combining section, and the output to the gain fiber can be individually improved and optimized and then the components are spliced together to create the finished device. Pump efficiencies of over 96% and power handling capabilities of 1.5kW have been demons ...

ABSTRACT: Nutronics, Inc. proposes to develop a detailed conceptual design for a general purpose, rugged, compact and lightweight beam director design for high energy laser phased array weapon systems. Our expertise in target based phase measurement approaches provides us with a unique insight into the basic requirements of both the subaperture for a phased array weapon system beam director and ...

ABSTRACT: The DoD requires accurate real-time knowledge of ionospheric variability in order to reduce one of the biggest error sources inherent in the use of critical systems such as Over the Horizon Radar (OTHR). OTHR is particularly susceptible to traveling ionospheric disturbances (TID"s) which are underspecified by current methods. Consequently, OTHR target location errors can reach 10s-100 k ...

ABSTRACT: The biggest demand on a military receiver has been from the time required to search and acquire for the military signals when an accurate internal time reference is not available. Prior research by NAVSYS into network assisted GPS approaches used the JTRS network itself to transfer time from another GPS receiver to reduce the initial time uncertainty and speed the acquisition time. This ...

Because of the overwhelming migration to composites, particularly exotic thermoset materials from the bismaleimide (BMI) family, the PNTS team is focusing its work on this topic on composite structures. The team's high level approach will be to demonstrate an innovative and practical design using dielectric spectroscopy at millimeter wave through terahertz frequencies that will provide compos ...
