Optical circular deflector with attosecond resolution for ultrashort electron beam
A novel method using high-power laser as a circular deflector is proposed for the measurement of femtosecond (fs) and sub-fs electron beam. In the scheme, the electron beam interacts with a laser pulse operating in a radially polarized doughnut mode (TEM01 ) in a helical undulator, generating angular kicks along the beam in two directions at the same time. The phase difference between the two a...
متن کاملProbing molecular dynamics at attosecond resolution with femtosecond laser pulses.
The kinetic energy distribution of D+ ions resulting from the interaction of a femtosecond laser pulse with D2 molecules is calculated based on the rescattering model. From analyzing the molecular dynamics, it is shown that the recollision time between the ionized electron and the D+2 ion can be read from the D+ kinetic energy peaks to attosecond accuracy. We further suggest that a more precise...
متن کاملCalibration of electron spectrometer resolution in attosecond streak camera.
We report a new method for determining the energy resolution of time-of-flight spectrometers for detecting photoelectrons produced with attosecond XUV pulses. By measuring the width of the 2s2p autoionization line of helium, we found the resolution of our spectrometer to be approximately 0.6 eV for electrons at 35.5 eV. Furthermore, the resolution in the 10 to 35 eV range was determined by appl...

متن کاملAttosecond pulses measured from the attosecond lighthouse
The attosecond lighthouse is a method of using ultrafast wavefront rotation with high-harmonic generation to create a series of coherent, spatially separated attosecond pulses. Previously, temporal measurements by photoelectron streaking characterized isolated attosecond pulses created by manipulating the single-atom response1–4. The attosecond lighthouse, in contrast, generates a series of pul...
