Abstract

Relative timing jitter between synchronized Q-switched lasers, or lack thereof, is important for stable sum-frequency generation. Experimental investigation of two passively synchronized lasers shows that the jitter is minimized when the free-running repetition rates of the two lasers are close to, but not exactly, matching. When the free-running repetition rates are matched, the jitter is significantly large. At the best operating point, the pulse-to-pulse period was 200 μs , while the relative jitter between the two lasers was 9 ns . If the effect of the master laser’s pulse-to-pulse jitter is removed, the residual timing jitter between the two lasers was 6 ns , which corresponds to the lower limit set by pump power fluctuations and noise from spontaneous emission.
