EXPERIMENTAL RESULTS ON OPTOGALVANIC EFFECT OF RUBIDIUM

We report, for the first time, the experimental results on the optogalvanic effect of Rb by using RF discharge without buffer gas. The influence of laser power and RF source current has been studied. The enhancement of the optogalvanic effect by heating the Rb cell and the optogalvanic signals of K as an impurity in Rb vapor have been observed.
