Paper Abstract

This paper deals with investigations of the spatial structure of the electrical potential, the current density, the gas temperature and the reduced electrical field strength in the discharge volume of a transverse gas flow CO2-laser in dependence on the geometry of the electrodes. The data were obtained by means bf Langmuir double probes. The results are compared with optical measurements applying a probe laser resonator. A calculation of the laser output power of a transverse flow laser is carried out on the base of rate equations including the convective losses. The position of the laser cavity in the gas flow direction is discussed to find optimum conditions.
