We measured the timing error of femtosecond pulses amplified by a Ti:sapphire regenerative amplifier operated at a 1 kHz repetition rate using a modified cross-correlation technique. This technique can detect sub-femtosecond timing variation. By actively controlling the amplifier cavity length, we reduced the rms timing jitter of the regenerative amplifier into the sub-femtosecond range.
