Fluorescence-Detected Mid-Infrared Photothermal Microscopy
Minghe Li, Aleksandr Razumtcev, Ruochen Yang +7
We demonstrate instrumentation and methods to enable fluorescence-detected photothermal infrared (F-PTIR) microscopy, then demonstrate the utility of F-PTIR to characterize the com…

Watt-level widely tunable single-mode emission by injection-locking of a multimode Fabry-Perot quantum cascade laser
Paul Chevalier, Marco Piccardo, Sajant Anand +7
Free-running Fabry-Perot lasers normally operate in a single-mode regime until the pumping current is increased beyond the single-mode instability threshold, above which they evolv…

Self-starting harmonic frequency comb generation in a quantum cascade laser
Dmitry Kazakov, Marco Piccardo, Yongrui Wang +7
Optical frequency combs establish a rigid phase-coherent link between microwave and optical domains and are emerging as high-precision tools in an increasing number of applications…
