ADVR, INC. — Department of Defense SBIR Phase I: AF151-080

Description

ABSTRACT:The development of compact, reliable inertial navigation systems is essential for applications where GPS-based systems are ineffective or unavailable. This Phase I SBIR will establish the feasibility of developing an ultra-stable, compact, robust, integrated laser source suitable for atom-based precision navigation and timing (PNT) systems. AdvRs design is enabled by capitalizing on well-commercialized, low-noise telecom components with high reliability and declining costs which will help to drive the widespread deployment of this system. The key innovation is the combination of current telecom-based fiber laser and modulator technology with periodically-poled waveguide technology to produce tunable laser light at rubidium D1 and D2 wavelengths (and expandable to other alkalis) using second harmonic generation (SHG). With this technology, multiple channels can be independently tuned to produce the fields needed in PNT applications.BENEFIT:The proposed project will develop integrated, compact laser that can be used as a source for atom-based precision navigation and timing (PNT) systems. In addition to the development of GPS-free systems, atomic based inertia sensors, and precision time keeping applications, this technology will have a broad range of uses including remote sensing for environmental monitoring, precision spectroscopy, high-security free-space communication, and basic research.
