Abstract

The temporal behaviour of the laser output characteristics has great influence on the quality and reproducibility of laser material processing. Changes in the transversal intensity distribution and fluctuations of the laser power during machining cause a decrease in processing quality. The interaction of laser medium with radiation field may be responsible for irregular behaviour of the laser beam parameters 1,2. In this paper experimental results concerning the influence of the active medium on the intensity distribution in the laser field and on the output power of the laser are presented. We have measured the stationary radial distribution of small signal gain and refractive index and in addition the instationary disturbance of the radiation field with fluctuations of the refractive index in a turbulent gas flow.
