Temporal lenses for attosecond and femtosecond electron pulses.
Here, we describe the "temporal lens" concept that can be used for the focus and magnification of ultrashort electron packets in the time domain. The temporal lenses are created by appropriately synthesizing optical pulses that interact with electrons through the ponderomotive force. With such an arrangement, a temporal lens equation with a form identical to that of conventional light optics is...
متن کاملSynchronization of femtosecond laser and electron pulses with subpicosecond precision
The temporal evolution of electron shadow images, formed by the projection of primary femtosecond electron pulses probe over a metal target and perturbed by the transient space-charge field near the target surface induced by the excitation of femtosecond optical pulses pump , is recorded in real time. By quantitatively analyzing the evolution of these shadow images as a function of pump-probe d...
متن کاملLocalized multiphoton emission of femtosecond electron pulses from metal nanotips.
Intense multiphoton electron emission is observed from sharp (approximately 20 nm radius) metallic tips illuminated with weak 100-pJ, 7-fs light pulses. Local field enhancement, evidenced by concurrent nonlinear light generation, confines the emission to the tip apex. Electrons are emitted from a highly excited nonequilibrium carrier distribution, resulting in a marked change of the absolute el...
متن کاملGeneration and characterization of tunable mid-infrared femtosecond pulses
In this Chapter we describe the design of an optical parametric amplifier that allows the generation of infrared laser pulses suitable for ultrafast nonlinear spectroscopy on the OH-stretching mode of water molecules. Mid-infrared femtosecond pulses, tunable in the range of 2800-3800 cm with sub-100 fs duration and ~15 μJ energy are produced by an optical parametric amplifier driven at 1 kHz by...
متن کاملGeneration and characterization of polarization-shaped femtosecond laser pulses
We demonstrate the generation and complete characterization of femtosecond laser pulses which change their intensity, frequency, and light polarization almost arbitrarily within a single pulse employing the new technique of femtosecond polarization pulse shaping. Specifically, the degree of polarization ellipticity as well as the orientation of the elliptical principal axes can be varied as a f...
