High-speed hyperspectral four-wave-mixing microscopy with frequency combs

Opt Lett. 2021 Aug 1;46(15):3556-3559. doi: 10.1364/OL.428172.

Abstract

A four-wave-mixing, frequency-comb-based, hyperspectral imaging technique that is spectrally precise and potentially rapid, and can in principle be applied to any material, is demonstrated in a near-diffraction-limited microscopy application.
