Abstract

The next-generation of fast, broadly tunable quantum cascade lasers (QCLs) is enabling the clinical translation of mid-infrared spectral imaging in high-throughput, high-confidence cancer screening. This new class of QCL source offers substantially faster tuning while also achieving superior wavelength scan-to-scan repeatability and reliability over extended operational periods. When integrated into a commercially-available wide-field QCL spectral imaging microscope [1-4], they can enable full-band chemical imaging of single biopsied tissue sections and of whole-slide samples to be conducted on the clinically relevant timescales of minutes and hours respectively.
