Paper Abstract

The spatial, temporal and spectral emission characteristics of radiation generated from electron oscillations driven by an intense circularly polarized laser pulse have been investigated theoretically and numerically using a single electron model. The motion of an electron is highly relativistic and head-on (180° ) collision of a single counter streaming electron and an intense circularly polarized laser pulse can produce a single ultrashort zeptosecond pulse along θ = 90° by merely using a few-cycle laser pulse with fixed carrier-envelope phase offset Φ0 = 0 without controlling phase φin [5] which is defined as the phase of the laser pulse when the electron enters it. An interesting modulated structure of the spatial characteristic is observed and analyzed.
