Abstract

A laser directional stabilization system corrects pointing errors in a laser used to transmit data in free space optical links. The system includes a nutator that nutates a laser beam over the face of an optical fiber at a receiver. Light entering the fiber is used as a sensor to achieve for stabilization. The laser beam is nutated at a single, relatively high frequency using resonant amplifiers driving linear actuators. Knowledge of the nutation command and the time varying intensity of light received at the center of the fiber permits generation an error that is used in a feedback loop to reduce laser pointing error.
