Fast frequency tuning and phase locking of diode-pumped Nd:YAG ring lasers.
We have built a diode-pumped single-mode monolithic Nd:YAG ring-laser oscillator that can be tuned piezoelectrically over several tens of megahertz in a few microseconds. Frequency stability over 1 msec is better than 500 Hz. We have electronically phase locked two lasers for periods of minutes with phase noise of 29 mrad rms.
