Optical Phase Locking in the Microradian Domain: Potential Applications to NASA Spaceborne Optical Measurements

Abstract
We have constructed and demonstrated a high-performance optical phase-locked loop between two cw ND-YAG lasers. The feedback system is relatively simple, employing only the laser's internal piezoelectric transducer and an external accousto-optic modulator. A residual phase noise of the order of 1 rad between two optical fields is achieved in the locked condition, as is verified by time- and frequency-domain analyses by the two-oscillator approach that is conventionally used in rf measuremnt. Potential applications to NASA space-based optical measurements are discussed.
