Fig. 2: Temporal (overlap between pump and control laser pulses) behavior of the ponderomotive shift.

a The photoelectron transient taken by fixing the pump laser at the blue-edge of the PhO− DBS 11′1 peak (denoted by the yellow shaded stick in Fig. 1b) while scanning the time-delay between the pump and control laser pulses. The transient was fitted with a Gaussian function. b Photodetachment spectra of the PhO− DBS taken at various delay times between pump and control pulses. The most prominent 11′1 band (centered at ~ 18,595 cm−1, black dashed line) shows the blue-shift and asymmetric broadening as the temporal overlap becomes maximized. The intensity of the non-resonant ps laser pulse (791 nm) was ~85 GW/cm2. Source data are provided as a Source Data file.
