DESCRIPTION (provided by applicant): The development of a durable, hemocompatible valve prosthesis is the long-term objective of this proposal. While heart valve prostheses have been used successfully since 1960, 10-year survival rates still range from

DESCRIPTION (provided by applicant): Cardiac assist devices are increasingly being used for long term support. As patient survival times increase substantially, long-term management of the patients will increasingly play a role in suitability of these

DESCRIPTION (provided by applicant): Cardiac assist devices are increasingly being used for long term support. As patient survival times increase substantially, device wear-out will increasingly play a role in the clinical management of patients with l

DESCRIPTION (provided by applicant): This Phase I SBIR application seeks support to develop a three dimensional acellular scaffold composed of particulate extracellular matrix (ECM). Products composed of the two dimensional (sheet form) of ECM der

As a cost avoidance measure against expensive replacement of certain life-limiting components of turbine engines, the Engine Rotor Life Extension (ERLE) program was conceived by the Air Force Research Laboratory (AFRL) to extend component life without increasing the risk of component failure. Nondestructive evaluation is one of many important components of ERLE which, if successfully implemented, ...

The objective of this Phase I effort is to design and simulate an innovative optical architecture for true, interactive-rate holographic video. Our novel technique takes a contrarian approach to existing multi-view and holographic video systems, which are typically crippled by "jailbar" dark regions, limited viewing zones, and image distortions arising from rendering techniques not intended for m ...

This Phase II SBIR will demonstrate the feasibility of applying spectral beam combining (SBC) to large mode area fibers to enable power scaling to the 100kW level while maintaining the excellent beam quality provided by a single fiber laser. The anticipated result of the Phase II and the Phase II option will be the laboratory demonstration of a beam-combined fiber laser system, and the subsequent ...

73137-Future active imaging systems for national security applications (for remote reconnaissance, monitoring and characterization of hard targets, and compact surveillance devices) require compact, rugged, and efficient short-pulse laser sources that can operate over a wide-repetition-rate range. To deploy these devices on ground, air, and space platforms, the new laser sources are required to i ...

The purpose of this program is to develop a compact and efficient ultraviolet laser system for ozone sensing from space. The basis for this system will be a diode-pumped neodymium-yttria (Nd:Y2O3) laser which is frequency-tripled to generate uv light at either 305nm or 315nm. The ability to generate both uv wavelengths from a single frequency-tripled Nd:Y2O3 laser makes this approach potentially 4 ...

We propose a Yb:S-FAP laser system that will provide over 1 J per pulse output at 100 Hz with excellent beam quality and high efficiency, in a package far more compact, and lighter weight than conventional laser systems. The proposed laser system uses design approaches compatible with space-qualification. The high-pulse-energy power oscillator architecture is especially suited to space platforms ...
