Timing jitter in a kilohertz regenerative amplifier of a femtosecond-pulse Ti:Al(2)O(3) laser.
We measure the timing error of femtosecond pulses amplified by a Ti:sapphire regenerative amplifier at a 1-kHz repetition rate by use of a modified cross-correlation technique. Linearly frequency-chirped amplified pulses are frequency mixed with transform-limited oscillator pulses. A shift in the sum frequency corresponds to the timing error of each amplified pulse relative to the oscillator pulses. The timing error was measured every 6 ms with approximately 1-fs resolution over a measurable range of 400 fs.
