Experimental data. a Histogram of the number of detected electrons from the interaction of few-cycle pulses with background gas only (red) and with 110 nm SiO2 particles (blue). b Average ion time-of-flight spectrum of shots containing nanoparticle hits on a mass/charge (m/q) axis. The indicated ionic fragments arise from ionization of argon and dissociative ionization of ethanol and water. The inset shows the enlarged peak of H+ on a momentum scale along the polarization direction (ppol), for events with SiO2 particles (blue) and with just background gas (red). The gray dashed lines indicate a momentum of ± 40 a.u. The Ar2+ peak is just indicated but is not visible on a linear scale
