We discuss and compare four methods for measuring the width and pulse profile of
ultrashort pulses. For our comparison, we use stable sub-7 fs pulses from a Ti: sapphire …

Spectro-temporal imaging (time-to-frequency conversion) constitutes a simple and direct
(single-shot) technique for the high-resolution measurement of fast optical temporal …

Pulses as short as 0.2 ps have been obtained from a passively mode locked dye laser. The
technique is simpler than those previously used, but one must pay the price of a loss of …

We describe a cross-correlation-based frequency-resolved optical gating (XFROG)
technique for simultaneously measuring the amplitude and phase of two ultrashort pulses …

We recently introduced a new technique, frequency-resolved optical gating (FROG), for
directly determining the full intensity I (t) and phase φ (t) of a single femtosecond pulse. By …

We observed the phase relation among subharmonic pulses generated by a femtosecond
optical parametric oscillator (OPO). The ratio of the optical frequencies of the idler, the …

We describe a new method—chronocyclic tomography—for determining the amplitude and
phase structure of a short optical pulse. The technique is based on measurements of the …

A new technique for optical sampling and time stretching of an analogue signal is presented.
The signal is 'wavelength stamped'by a chirped optical pulse. An arrayed waveguide grating …

The use of temporally shaped pump pulses for optical parametric chirped-pulse
amplification can increase the efficiency and suppress possible spectral distortions in this …
