We demonstrate the on-target temporal characterization of sub-4-fs pulses by third-harmonic dispersion-scan, using a minimal in-line setup where a gas target optimized for high-harmonic generation doubles as nonlinear medium, obtaining excellent agreement with independent SEA-F-SPIDER measurements.
