Common pulse retrieval algorithm: a fast and universal method to retrieve ultrashort pulses

Pulse front adaptive optics: a new method for control of ultrashort laser pulses.

Ultrafast lasers enable a wide range of physics research and the manipulation of short pulses is a critical part of the ultrafast tool kit. Current methods of laser pulse shaping are usually considered separately in either the spatial or the temporal domain, but laser pulses are complex entities existing in four dimensions, so full freedom of manipulation requires advanced forms of spatiotempor...

Measuring pulse-front tilt in ultrashort pulses using GRENOUILLE.

We show that the spatio-temporal distortion, pulse-front tilt, is naturally, easily, and sensitively measured by the recently demonstrated, extremely simple variation of single-shot second-harmonic generation frequency-resolved optical gating (SHG FROG): GRENOUILLE. While GRENOUILLE traces are ordinarily centered on the zero of delay, a pulse with pulse-front tilt yields a trace whose center is...

Ultrashort Pulses

Ultrashort pulses usually are defined as those lasting less than a nanosecond. Low-energetic ultrashort pulses can be used, for instance, as a probe for studying the dynamics of ultrafast processes. Amplifying these pulses can deliver extremely high peak power, allowing applications such as laser particle acceleration, or γ-ray generation via Compton scattering on relativistic electrons. Existi...

A Quasiperiodic Approach to Ultrashort Pulses

Using phase retrieval to measure the intensity and phase of ultrashort pulses: frequency-resolved optical gating

Received September 16, 1992; accepted October 9, 1992; revised manuscript received December 1, 1992 We recently introduced a new technique, frequency-resolved optical gating (FROG), for directly determining the full intensity I(t) and phase p(t) of a single femtosecond pulse. By using almost any instantaneous nonlinearoptical interaction of two replicas of the ultrashort pulse to be measured, F...
