Abstract
We generate continuously wavelength-tunable truncated laser pulses with a high-pressure (11 bar) single-mode 10 micrometers CO2 laser and a plasma shutter and applied them to an optical-free-induction-decay (OFID) system. Single- mode operation is achieved using a 3-mirror resonator with etalon. A detailed analysis of this resonator type is presented.
