Sub-picosecond laser timing stabilization

Abstract-The 0.25 Hz-25 kHz pulse timing fluctuations of a Nd:YAG CW-mode-locked laser are reduced from 20.6 ps to less than 0.30 ps rms by an electronic phase-lock loop. Stabilizer design consid-erations include the laser phase control characteristics, phase detector additive noise, and spurious detection of the laser amplitude noise by the loop phase detector. Applications include synchronization of mul-tiple picosecond pulsed lasers, and synchronization of lasers and elec-tronic signal sources in picosecond physical measurements. I
