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 PZT and an external acousto-optic modulator. A residual phase noise on the order of 1 microradian between two optical fields is achieved under the locked condition. This is verified by time- and frequency-domain analysis using a two-oscillator approach conventionally used in the rf measurement. Potential applications to NASA space-based optical measurements are discussed.Citation
