A Microwave Resonator for Studying Chemical Laser Reactions

Abstract
A near semiconfocal Fabry‐Perot resonator has been integrated with a small chemical laser to permit detection of ground and excited vibrational state rotational transitions of the reaction products within the laser cavity without perturbing the laser system. The effective lifetimes of unstable gas‐phase species can also be followed by monitoring the maximum value of the absorption coefficient.
