Laser Beacon for Identification, Friend or Foe (IFF) and Combat Identification

This proposal describes the development of a Laser Beacon system concept that initially provides dual high-power emission at 1064 nm and 4.6 microns. Commercial-off-the-shelf (COTS) 1064-nm laser diodes will be tailored to provide the optical output intensity required for detection by targeting pods. Quantum cascade laser technology will be utilized to provide emission in the mid-wave infrared (MWIR) spectral band at 4.6 microns. Size reduction of the current laser design will be investigated for development of a small MWIR emitter. The optical emitters will be integrated with an onboard programmable microprocessor that controls the emission modulation. An initial packaging and electrical design will be developed for use as a handheld lightweight unit. The expected detection performance as a function of range will be modeled for operational targeting pods and sensors. A draft functional specification for the Laser Beacon system will be developed based on the trade-off study between size, weight, and operating parameters. A system concept design will be provided at the end of this effort. BENEFIT: The anticipated benefits of the proposed approach for this project will provide the development of a unique IFF and CID handheld device. The proposed device could be modified for targeting applications where the MWIR emission would provide a visual verification of the target and the 1064 nm emission would provide guidance for the ordinance. Potential commercialization applications would be for outdoor hiking safety. The beacon would provide a visual locating system for airborne search and rescue platforms for personnel in distress. The beacons would also provide a visual tracking device for search and rescue teams if communications via radio were not available.
