Abstract

The detection of the Lamb-dip in the transition of nitrous oxide at 1174.05 wavenumbers was studied using cavity-enhanced absorption and NICE-OHMS spectroscopy. In this study a quantum cascade laser (QCL) operating at 8.5 microns was tightly locked using the Pound-Drever-Hall technique to a 26.8 cm long optical cavity formed by two mirrors mounted inside a gas cell. The demodulated signal and the dispersion feature corresponding to the Lamb-dip was shown.
