Abstract
The dual-control of the delay and phase noise characteristics of a passively mode-locked Ti:sapphire laser was studied using a frequency-stabilized piezoelectric transducer (PZT) controlled end-mirror. The controlling circuit for the PZT/mirror set is implemented by integrating a digital optoelectronics phase-locked loop (OEPLL). The results showed that the delayed laser pulse-train were observed with maximum pulsewidth, tuning range, and rms timing jitter of 130 fs, 11.3 ns, 2.3 ns/volt, and 290 fs.
