Va. Zaporozhchenko et Na. Tylets, TEMPORAL LOCKING OF OPTICAL PULSES TO EXT ERNAL SIGNAL IN PULSE LASERS WITH ACTIVE MODE-LOCKING, Kvantovaa elektronika, 23(6), 1996, pp. 527-531
The cross-correlation measurements of jitter between pulses of two act
ively mode-locked and Q-switched lasers were fulfilled at the differen
t ways of their synchronization: by the common mode-locker drive signa
l and by the electrical sync pulse. Due to prelase stabilization by th
e negative feedback loop the fluctuations of ultrashort pulse timing r
elatively mode-locker drive signal have been reduced to +/-10-15 ps. T
he accuracy +/-130 ps of the ultrashort pulse locking td the external
trigger sync pulse have been achieved.
