Comb-locked cavity ring-down spectroscopy of CO2 at 2-micron wavelength
Muhammad Asad Khan, Vittorio D'Agostino, Stefania Gravina +2
We report on a comb-locked cavity ring-down spectrometer developed for high-precision, SI-traceable, molecular spectroscopy of air-broadened CO2 gas samples. The experimental setup…
Cavity ringdown spectroscopy at 2 m wavelength assisted by a comb-locked optical parametric oscillator
Vittorio D'Agostino, Eugenio Fasci, Muhammad Asad Khan +3
We report on a comb-locked cavity ring-down spectrometer developed for high-precision molecular spectroscopy at 2 m. It is based on the use of an external-cavity diode laser tha…
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…
