Emission and its back-reaction accompanying electron motion in relativistically strong and QED-strong pulsed laser fields.

چکیده
The emission from an electron in the field of a relativistically strong laser pulse is analyzed. At pulse intensities of J>or=2x10(22) W/cm(2) the emission from counterpropagating electrons is modified by the effects of quantum electrodynamics (QED), as long as the electron energy is sufficiently high: E>or=1 GeV . The radiation force experienced by an electron is for the first time derived from the QED principles and its applicability range is extended toward the QED-strong fields.

Radiative reaction in ultra-intense laser–atom interaction
The influence of the radiation of an initially bound electron in an ultra-intense laser field on its dynamics and the consequent corrections to its spectral response are investigated within the relativistic classical Lorentz–Dirac approach. We find appreciable damping of the electron motion in the direction of polarization of the laser field, and a consequent reduction of the electron oscillati...
متن کاملDelayed electron emission in strong-field driven tunnelling from a metallic nanotip in the multi-electron regime
Illuminating a nano-sized metallic tip with ultrashort laser pulses leads to the emission of electrons due to multiphoton excitations. As optical fields become stronger, tunnelling emission directly from the Fermi level becomes prevalent. This can generate coherent electron waves in vacuum leading to a variety of attosecond phenomena. Working at high emission currents where multi-electron effec...
متن کاملThe electronic g-factor in hydrogen-like ions
The precise calculation of the anomaly of the magnetic moment of the elect ron is one of the great successes of QED. According to Dirac theory, the gfactor, which indicates the size of the magnetic moment in multiples of the Bohr magneton eh/ 2 me, should be exactly 2. With QED it is possible to precisely calculate the small deviation from the value 2 which is due to the influence of the cloud ...
متن کاملAttosecond Control of Relativistic Electron Bunches using Two-Colour Fields
Energy coupling during relativistically intense laser-matter interactions is encoded in the attosecond motion of strongly driven electrons at the pre-formed plasma-vacuum boundary. Studying and controlling this motion can reveal details about the microscopic processes that govern a vast array of light-matter interaction physics and applications. These include research areas right at the forefro...
متن کاملPropagation and Interaction of Electrostatic and Electromagnetic Waves in Two Stream Free Electron Laser in the Presence of Self-Fields
A relativistic theory for two-stream free electron laser (FEL) with a one-dimensional helical wiggler and ion-channel guiding in the presence of self-fields are presented. A dispersion relation (DR) which includes coupling between the electromagnetic and the electrostatic waves is derived from a fluid model, with all of the relativistic terms related to the transverse wiggler motion. This DR is...
