Paper Abstract

The influence of carbon-dioxide impurity within the laser medium on energy and spectral characteristics of pulsed chemical HF and DF lasers working on chain process has been experimentally investigated. An increase of the concentration of the carbon-dioxide impurity within the laser medium from 0.1 up to 0.6% caused the five-fold reduction in energy and in suppression of generation of about 50 spectral lines of six high bands. The sensitivity of the energy characteristics of the HF laser to the change of the carbon-dioxide concentration was an order of magnitude smaller than for the DF laser, in this case the appreciable changes in the HF laser spectrum were not observed. It is shown, that at low carbon-dioxide concentration (less than 0.1%) the achievement of equal specific output energies per HF and DF molecules is possible.
