Experimental challenges are imposed both by the use of a pulsed light source and by the need for interferometric signal modulation to isolate the near\u2010field contribution. We present a novel experimental approach to retrieve the tr\u2010SNOM signal using a 200\u2010kHz laser system and pseudo\u2010heterodyne modulation. We circumvent the Nyquist limit for spectral demodulation by sampling modulation phases, pump intensity, and SNOM signal for every laser shot. A general time\u2010resolved SNOM signal is derived, independent of the detection scheme or physical assumptions about the near\u2010field enhancement, and is successfully measured and isolated on WS\n                    <jats:sub>2<\/jats:sub>\n                    monolayer and multilayer regions. We confirm localization by signal\u2013distance curves, spatial confinement at material boundaries, and by identifying signal contributions at individual modulation harmonics. Disentangling the dynamic contributions enables us to extract the dynamic dielectric function of the sample. Showing the capability of phase\u2010domain sampling paves the way to the integration of more diverse and specialized light sources, growing the potential of optical ultrafast near\u2010field measurements.\n
