Dual-Comb Photothermal Microscopy

Published 24 Sep 2024 in physics.optics | (2409.15685v1)

Abstract: We introduce a new parallelized approach to photothermal microscopy that utilizes mid-infrared dual-comb lasers, enabling simultaneous measurements at hundreds of wavelengths. This technology allows for high-speed, label-free chemical identification with super-resolution infrared imaging, overcoming the limitations of slow, single-wavelength-laser methods.
