An intracavity spectrometer with an additional channel for recording emission spectra is presented. The spectrometer is capable of recording weak absorption spectra of radicals in plasma with high threshold sensitivity, as well as monitoring the molecular composition of a gas mixture using visible and UV emission spectra with time resolution of 25 ns.
