Abstract

Time and spatial profiles of the density were directly measured for the lower level (²D_5/2) as well as the upper level (2P_3/2) of a copper vapor laser (CVL). A significant spatial dependent population of the lower level was observed. It was higher at the center than near the wall of a 42 mm diameter tube at just before discharge. On the other hand, a slight radial dependence was detected for the upper level. These radial dependent densities presumably resulted in the spatial dependent gain of the CVL.
