Abstract

A method to generate stable single longitudinal mode (SLM) radiation from a multi-interferometric cavity configuration that can be considered as the combination of one Michelson cavity and two Fox–Smith cavities is presented. A numerical model of the interferometric cavity is investigated to optimize the laser for mode selection, and experimental verification has been carried out in a tunable TEA CO2 laser. Pulse output energy of 300mJ at 10.6μm has been obtained at repetition rate of 20Hz, corresponding to a repetition of SLM operation of 100%. This result shows that this interferometric cavity gives better performance in mode selection than other cavities based on multibeam interference.
