Generation and Measurement of 50-fs (rms) Electron Pulses

Generation and Me~urernent of 50 Fs(rms) Electron

An electron source h~ been developed at the Stanford SUNSHINE SLAC-P~-6507 SLAC/SSRL-0078 June 1994 (~SSRL-ACD)

Sub-fs electron pulses for ultrafast electron diffraction

We present a new concept for an electron gun generating subrelativistic electron pulses with a duration down to the attosecond range. It is based on a cylindrical RF cavity (a so-called pill-box cavity) oscillating in its TM010 eigenmode with a photocathode triggered by a fs-laser pulse. Injecting electrons at an appropriate phase of the RF cycle compensates for their initial velocities and tim...

Measurement of subpicosecond electron pulses.

A new bunch-length measuring method has been developed to measure the subpicosecond electron pulses generated at the Stanford SUNSHINE facility. This method utilizes a far-infrared Michelson interferometer to measure coherent transition radiation emitted at wavelengths longer than or equal to the bunch length via optical autocorrelation. To analyze the measurement, a simple and systematic way h...

Generation of 150-fs tunable pulses in Cr:LiSrAlF6.

Generation of intense 8-fs pulses at 400 nm.

Frequency-doubled pulses from a sub-40-fs, 1-kHz Ti:sapphire amplifier system are spectrally broadened in an argon-filled hollow waveguide. Compression of the self-phase-modulated pulses is implemented with chirped mirrors and a prism pair, yielding 8-fs, 15-muJ pulses in the violet spectral range.
