Abstract
In the article is described the construction of a cw GDL based on combustion of CO, with the mixture exhausted to the atmosphere through a supersonic diffuser, as well as apparatus for the investigation of the physical properties of the active medium. The flow rate of the vibrational quanta converted into laser radiation at the input to the optical resonator is determined by calculation and experimentally. The main properties of the GDL active medium are investigated. The total losses in the optical resonator are determined and their influence on the output power is calculated. The operating conditions of the gasdynamic layer are experimentally optimized. A resonator with additional feedback is proposed.
