Polarization-Resolved High Harmonic Spectroscopy of Interlocked Attosecond Bursts

Abstract

High-harmonic spectroscopy is an important tool for investigation of nonlinear atom-laser interaction [1]. Polarization-resolved high harmonic spectroscopy is becoming a promising method for exploring chiral quantities, in particular as numerous techniques have been demonstrated experimentally for generating bright and applicable high-order harmonics with highly helical polarization [2,3]. In this context, a simple direct mapping (ideally, analytical formula) between the harmonics polarization and time-domain description of the HHG process would be very useful.
