Dual-Comb Photothermal Microscopy
Peter Chang, Ragib Ishrak, Nazanin Hoghooghi +4
We introduce a new parallelized approach to photothermal microscopy that utilizes mid-infrared dual-comb lasers, enabling simultaneous measurements at hundreds of wavelengths. This…
Mid-Infrared Hyperspectral Microscopy with Broadband 1-GHz Dual Frequency Combs
Peter Chang, Ragib Ishrak, Nazanin Hoghooghi +7
Mid-infrared microscopy is an important tool for biological analyses, allowing a direct probe of molecular bonds in their low energy landscape. In addition to the label-free extrac…
1-GHz mid-infrared frequency comb spanning 3 to 13 μm
Nazanin Hoghooghi, Sida Xing, Peter Chang +4
Mid-infrared (MIR) spectrometers are invaluable tools for molecular fingerprinting and hyper-spectral imaging. Among the available spectroscopic approaches, GHz MIR dual-comb absor…
