washing ton repor t DOD ISSUES FY2010 STTR SOLICITATION TOPICS The Department of Defense has announced the “pre-release” of its first FY2010 Small Business Technology Transfer (STTR) solicitation. The solicitation covers a variety of Army and Navy topics, including several EW initiatives. The Army’s STTR solicitation describes a project titled, “Coherent Beam Combining of Mid-IR Lasers” (Topic A10a-T007). Under this effort, the Army is seeking research into development of “robust, high-efficiency mid-infrared lasers based laser beam combining of quantum cascade or other mid-IR laser diodes.” The objective is to achieve power outputs of “several to a hundred Watts” in the 3- to 5-micron and 8- to 12-micron bands for IR countermeasures (IRCM) and stand-off sensing applications. DARPA has already funded development of quantum cascade lasers (QCLs) in the 4- to 5-micron band for IRCM applications, and the Army has supplemented this work with initial QCL research into the 3-5 and 8-12 micron bands. This effort would continue that work by demonstrating a “design of beam-combined high performance midIR laser arrays based on QCLs or other semiconductor lasers with power output of 3W or more (i.e. greater than state-ofthe-art output power over single lasers with comparable wall-plug efficiencies).” The topic point of contact is Mike Gerhold, (919) 549-4357, mike.gerhold@ Another project in the Army solicitation is titled “Photonic Amplifiers Based on III-nitrides Grown on Si Substrates” (Topic A10a-T015). This effort will investigate development of a new class of photonic amplifiers to be used in communications and countermeasures applications. Phase I research will focus on “proof-of-concept of a technology for grow th of III-nitride photonic device structures on Si substrates.” The topic point of contact is John Zavada, (919) 549-4238, The Navy STTR solicitation included several directed-energy and EW-related research topics. Naval Sea Systems Command’s Directed Energy and Electric Weapon Systems Program Office (PMS405) is supporting a project titled, “High Efficiency Gain Media for Eye-Safer 1.55 μm Ultrafast Fiber Amplifiers” (Topic N10A-T012). This effort will focus on developing a “high efficiency erbium glass gain media optical amplifier to scale the average power of eye-safer ultrafast fiber laser sources,” for use in directed energy weapons, IRCM applications and LADAR. The topic point of contact is J. Thomas Schriempf, (202) 781-1196, john. Another Navy research project, titled “Optical Cooling or RF Systems (Topic N10A-T017) will investigate optical cooling techniques that may be useful in removing heat from RF apertures and amplifiers. Aimed at supporting the Navy’s Surface EW Improvement Program (SEWIP), the research will focus on designing a scheme for cooling high-power density (e.g., GaN) power amplifiers using the anti-Stokes effect. Initial experimentation should prove a net cooling can be obtained and determine the general principles that apply to optimizing the design.” The topic point of contact is Deborah Van Vechten, (703) 696-8496, deborah.vanvechten@ NAVSEA’s JCREW/EOD Program Office (PMS-408) is sponsoring a project titled “Wideband Metamaterial Antennas Integrated into Composite Structures” (Topic N10A-T021), which will “develop methodologies and manufacturing processes for integrating the antenna’s conductive elements and devices directly into the composite structures of the platform such as ship topside superstructure or Marine Corps vehicles.” Phase I work will focus on material/componentlevel modeling of integrated wideband antenna concepts. The work should result in one or more candidate designs for a wideband antenna integrated within a composite structure. The topic point of contact is Dave Tremper, (703) 696-0065, In the directed energy arena, the Free Electron Laser Innovative Naval Prototype (FEL INP) program at the Office of Naval Research (ONR) is sponsoring research into “Development of HighEfficiency, High-Power Electron Beam Accelerator Technologies” (Topic N10AT023). This project aims to develop technologies supporting the development of a mega-watt class electron beam accelerator for ship self-defense applications. “Research will focus on novel strategies for designing and developing high quantum efficiency (>5%), long life cathodes for use in high duty factor DC, normal conducting RF and superconducting RF guns.” Phase I work will cover development of design for both the accelerator components and associated test equipment. The topic point if contact is Dr. Eugene Nolting, (202) 781-3175, Eugene. The proposal deadline for these topics is March 24. The Army and Navy expect to award one or two Phase I contracts for each study topic. Awards will not exceed $100,000, and studies will run for six months. A small number of these contracts will be selected for further research and development.
