Attosecond pulse generation in laser-assisted radiative recombination — •Katarzyna Krajewska1, Deeksha Kanti1, Jerzy Z. Kaminski1, and Liang-You Peng2 — 1University of Warsaw, Warsaw, Poland — 2Peking University, Beijing, China
Electron-ion radiative recombination in the presence of a bicircular laser pulse is analyzed beyond the dipole approximation [1]. A bicircular pulse consists of two counter-rotating circularly polarized laser pulses with commensurate carrier frequencies. It is demonstrated that the broad bandwidth radiation can be generated in the process and that its spectrum can be significantly enhanced by tailoring the laser field [2]. A special emphasis is put on analyzing temporal properties of generated radiation, which is released as either an isolated attosecond pulse or an attosecond pulse train.
