Reflective high-finesse interferometers as effective intrapulse laser frequency stabilizers.
The effect of optical cavity length perturbations on the intrapulse frequency stability of laser cavities terminating in reflective multipass interferometers is investigated. We demonstrate both theoretically and experimentally, in a long-pulse single-mode TEA CO(2) laser, that intrapulse frequency chirping can be strongly reduced by using relatively long high-finesse interferometers. These results can be applied to the design of single-mode lasers with negligible chirping.
