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 ...

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 ...

NIST is using a sensitive optical technique called cavity ring-down detection to permit detection of impurities in semiconductor process gases, which cause substantial losses in manufacturing yield. In order to increase the sensitivity and range of application of this technique, improved single frequency laser sources are required. In particular, lasers providing more power, narrower line-width, b ...

Optically pumped, high power, mid-Infrared semiconductor lasers that operate at cryogenic temperature must be engineered to operate over large ambient temperature and harsh vibration environments to be able to be used in future IRCM systems. The proposed work will demonstrate novel methods of laser packaging that enable operation of a low cost, mid-infrared, semiconductor laser in military tempe ...

The Navy requires high power laser sources that can provide multi-Watt output power levels in the mid-infrared for optical countermeasures of anti-ship missiles. Current state-of-art laser transmitters, consisting of diode-pumped solid-state lasers and optical parametric oscillators, have demonstrated the required optical power and wavelength in the mid-infrared spectral region. However, these l ...

The Future Combat System (FCS) military diesel engine propulsion systems tribological considerations are predicted to be compromised primarily by the temperature capability of the lubricating fluid. Thermal oxidation resulting in lubricant work in rigid condition breakdown and formation of deposits are typical causes of engine failure at high temperature operating conditions. Work in the Phase I ...

The objective of this proposal is to develop and demonstrate methods for extending the Battlespace Infosphere to small, mobile and embedded systems using optimized COTS technologies. The USAF Scientific Advisory Board report titled Building the Joint Battlespace Infosphere identifies XML as one of the most promising technologies for representing information objects. Many DoD organizations have ado ...

Given two closely related pieces of software X and Y, where Y differs from X through a number of small but important (from a security point of view) modifications that were done to Y, the "diff" attack consists of comparing X and Y so as to pinpoint the fragments of code in which they differ. The differences between X and Y could include, among other things, the fact that Y contains credentials-c ...

The Missile Defense Agency (MDA) requires the capability to provide cryogenic cooling for infrared sensing, cryogen management, electronics cooling, and superconductivity for long term (over five year) space missions. Multistage cryocoolers have the potential to reduce the number of coolers needed on a spacecraft and, and therefore, reduce overall system mass and power consumption, and improve re ...

Candent Technologies is developing an innovative small gas turbine engine capable of improved fuel efficiency and low production and development costs. This engine system is applicable to the next generation of unmanned aircraft systems. The Phase II program will conduct a full scale demonstration of this innovative engine technology.
