Technical Abstract (Limit 2000 characters, approximately 200 words)

AOSense proposes to develop compact laser amplifier modules for cold-atom optical systems. The device would deliver > 1 W of power in optical fiber at 852 nm when paired with an appropriate narrow-linewidth master laser oscillator. A key feature is the integration of a tapered amplifier with AOSense-proprietary compact, high transmission optical isolators, yielding a fiber-in, fiber-out package with dimensions of 50 mm x 65 mm x 35 mm or smaller. This amplifier module has broad applicability to atom interferometers and atomic clocks, but it would be particularly useful for high-performance orbital sensors like Atom Interferometer Gravity Gradiometers (AIGG). Such systems will likely utilize advanced atom-optic laser pulse sequences, which require more laser power to mitigate atom losses and achieve high sensitivity.

Potential NASA Applications (Limit 1500 characters, approximately 150 words)
  • Earth and planetary static and time-variable gravity mapping
  • Asteroid tomography for rendezvous or planetary defense
  • Gravitational wave detection and tests of fundamental physics
  • Gyroscopes and inertial guidance for deep-space navigation
  • Atomic clocks for GPS and communication
  • Magnetometers for space vehicles
Potential Non-NASA Applications (Limit 1500 characters, approximately 150 words)
  • Gravity surveys, for example, the National Geodetic Survey (NGS)
  • Oil, gas, and mineral exploration
  • Inertial navigation to aid GPS or in GPS denied environments
  • Tomographic restricted material monitoring
