Observing the intrinsic linewidth of a quantum-cascade laser: beyond the Schawlow-Townes limit
S. Bartalini, S. Borri, P. Cancio +6
A comprehensive investigation of the frequency-noise spectral density of a free-running mid-infrared quantum-cascade laser is presented for the first time. It provides direct evide…

Saturated-absorption cavity ring-down spectroscopy
G. Giusfredi, S. Bartalini, S. Borri +4
We report on a novel approach to cavity-ring-down spectroscopy with the sample gas in saturated-absorption regime. This technique allows to decouple and simultaneously retrieve emp…
