Paper Abstract

The design and performance of a CO2 CW EDL are described. Particular emphasis is given to the effects of medium inhomogeneities and mode medium interaction on the properties of the output beam. Experimental results show medium density profiles, predominantly linear, quadratic and cubic, arising from the heating due to power loading of the gas. Fluctuations in the output flux are also shown. These arise from the interaction of the mode flux with the medium. The variation of this interaction with device parameters on beam quality is discussed. Experimental results showing a minimal impact of mode-medium effects on beam quality are shown.
