Title:METROLOGY WITH AN OPTICAL FEEDBACK FREQUENCY STABILIZED CRDS
Author(s):Kassi, Samir
Contributor(s):Burkart, Johannes
Subject(s):Mini-symposium: High-Precision Spectroscopy
Abstract:We will present a metrological application of our recently developed Optical Feedback Frequency Stabilized - Cavity Ring Down Spectrometer (OFFS-CRDS). This instrument, which ideally fits with an optical frequency comb for absolute frequency calibration, relies on the robust lock of a steady cavity ring down resonator against a highly stable, radiofrequency tuned optical source. At 1.6 $mu$m, over 7 nm, we demonstrate Lamb dip spectroscopy of CO$_2$ with line frequency retrieval at the kHz level, a dynamic in excess of 700,000 on the absorption scale and a detectivity of 4x10$^{-13}$cm$^{-1}$Hz$^{-1/2}$. Such an instrument nicely meets the requirements for the most demanding spectroscopy spanning from accurate isotopic ratio determination and very precise lineshape recordings to Boltzmann constant redefinition.
