title: Longitudinal-mode selectivity and perturbation sensitivity of multimirror laser cavities.
abstract: Some relevant features of a particular type of multimirror laser cavity, i.e., those cavities terminating in highfinesse reflective multipass interferometers, are theoretically investigated with the aim of highlighting the dependence of the level of spectral control achievable with these cavities on their geometrical and optical characteristics. It is shown that cavities equipped with suitably designed reflective multipass interferometers are not only capable of forcing a laser operation on a single longitudinal mode but can act at the same time as effective emission frequency stabilizers because of their inherently low sensitivity to any perturbation affecting the cavity optical length. This feature is particularly attractive for intrapulse and pulse-to-pulse stabilization of high power pulsed lasers. Criteria are given also for the design of optimized cavities that could simultaneously provide narrow linewidth laser emission and minimize the effects of perturbations.
