Advanced Tunable Laser (ATLAS)

ABSTRACT: A multi-functional laser (MFL) is becoming an essential component of a prospective active laser system for tracking, characterization and discrimination of space objects. Low intensity, object-returned signals in combination with its large Doppler frequency shift requires novel solutions to address the issues necessary to facilitate steady-track conditions. This proposal outlines the AS & T approach in designing an MFL and the validation of a fast-tunable, frequency-controlled CW laser that is required for high MFL performance. This Phase I program will focus on performance analysis and proof of principle experiments of the proposed Advanced Tunable Laser (ATLAS) module. During Phase II of this program we will perform a prototype MFL system design including integration and laboratory validation. BENEFIT: The proposed ATLAS should support a number of applications including LADAR and laser tracking systems, high-density optical storage systems, optical non-destructive testing systems, high-resolution profilometers, and sensors based on fiber-Bragg gratings. Additionally, in combination with an amplifier stage, the described laser system would be an ideal pump source for narrowband optical-parametric oscillators (OPO) for the remote sensing of atmospheric trace gases.
