ORCLS - Optical-Radio Coherence for Laser Stability

Completed Technology Project

Project Introduction

ORCLS - Optical-Radio Coherence for Laser Stability
GRACE 2 laser ranging precision is limited by laser frequency stability. The laser reference cavity meets short-term stability requirements, but fails long-term requirements by a factor of 10. ORCLS uses ultra-stable GPS to provide long-term stability readout. No flight missions to date have incorporated a long-term optical frequency reference. The main products will be a TRL-3 proof of concept of laser frequency relative to RF source and a TRL-4 breadboard demonstration of design appropriate for implementation on GRACE 2. More »
