A double-cavity optical configuration designed to investigate the sensitivity of intracavity absorption in a cw multimode dye laser is reported. The configuration consists of two optical cavities coupled together through a common partially transmitting mirror. An atomic beam of sodium is used as a low-density absorber to compare the sensitivity of a double-cavity configuration with that of a single cavity. The results are that the sensitivity of the double-cavity system is about half of that obtained with the usual single cavity. An interpretation of the results is made in terms of the super-regen model of intracavity absorption.
