Figure 1. Experimental set-up and conditions.
Top: schematic of the experimental set-up. (a) Spatiospectral profile in the gas jet focus without WFR. (b) Corresponding calculated electric field. (c) Measured HHG spatiospectral profile generated in 1-bar Argon without WFR. (d) Spatiospectral profile in the gas jet focus with WFR. (e) Corresponding calculated electric field. (f) Measured HHG spatiospectral profile generated in 1-bar Argon with WFR, revealing a 4-mrad separation between beamlets.
