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…
