Abstract

The tuning in delay-time and suppression in phase noise (or timing jitter) of an Ar⁺-laser-pumped, passively mode-locked femtosecond Ti:Sapphire laser with intracavity saturable Bragg reflector (SBR) is demonstrated by integrating the laser with an actively-stabilized frequency-discriminating delay-locked loop. The delayed laser pulse-train with maximum pulsewidth, tuning range, gain, and rms timing jitter of 130 fs, 11.3 ns, 2.3 ns/volt, and 290 fs (< 500 Hz) are reported.
