Technical Abstract

AOSense proposes to develop laser amplifier modules for cold-atom optical systems. The device would deliver > 1 W of optical power at 852 nm by fiber 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 50 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 (AIGGs). 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

• 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

• 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
