A system for locking a laser with a resonant optical cavity includes a laser that emits a laser
beam, a resonant optical cavity having at least two cavity mirrors, one of which is a cavity …

A simple and universal technique for performing optical feedback cavity enhanced
absorption spectroscopy with a linear Fabry-Pérot cavity is presented. We demonstrate …

Abstract In general, Cavity-Enhanced Absorption Spectroscopy (CEAS) suffers from
inefficient and noisy cavity injection when using an unstabilized laser source with a linewidth …
