Abstract

The performance of a simple resonator that couples a reflective multipass interferometer cavity and a Fabry-Pérot etalon to obtain high efficiency tunable single-longitudinal mode (SLM) oscillation in a TEA CO2 laser is reported. A numerical model of the resonator was explained to predict the mode behavior of the laser as well as to optimize the resonator to achieve SLM operation, and the predicted mode characters are experimentally verified.
