摘要：

An optical pulse autocorrelator is described which allows online measurement of femtosecond pulse profiles of tunable light sources having 100 Hz-10 kHz repetition rates. The device is capable of dispersion-free noninterferometric measurement of pulse durations ranging from about 100 to sub-10 fs. The applicability of the device is demonstrated in the wavelength range from 420 to 1460 nm. The time delay is scanned with a simple open-loop piezoceramic translator, which is interferometrically calibrated. The accuracy of the device is verified by comparing an autocorrelation trace of a 10 fs pulse with the autocorrelation computed from a zero-additional-phase-spectral phase interferometry for direct electric field reconstruction (ZAP-SPIDER) measurement in the visible region. Its compact design and high sensitivity make the autocorrelator an ideal tool for the diagnostics of tunable ultrashort pulses. (C) 2004 American Institute of Physics.
