Photoelectron circular dichroism in fenchone by short coherent broadband laser pulses
PHYSICAL REVIEW A(2023)
摘要
Photoelectron circular dichroism (PECD) of fenchone induced by short coherent broadband laser pulses is studied theoretically using the time-dependent single-center method. In particular, we investigate the chiral response to circularly polarized pulses with a sine-squared energy spectrum between 1 and 3 eV. We consider nonchirped and differently chirped pulses of a moderate peak intensity of 3 x 1012 W/cm2 and a nonchirped pulse of a higher peak intensity of 1 x 1014 W/cm2 leading to a strong-field ionization. Thereby, effects of the frequency ordering and pulse intensity are investigated in some detail. The present theoretical study predicts a substantial multiphoton PECD of fenchone, which can be manipulated by tailoring a spectral phase and intensity profile of a single coherent broadband laser pulse.
