Abstract

The dissociated bromine in CuBr laser has serious effects on the life-time of CuBr laser and the stability of the discharge plasma so it is important for the long-lived sealed-off CuBr lasers. The adsorption of bromine on the surface of the copper around the electrodes was measured by an X-ray Energy Dispersive Spectrometer. It is found that the dissociated bromine from CuBr molecule after collision in the laser discharge plasma is negative bromine ion, no positive bromine ion existed. On the average the atomic percentage of the adsorbed bromine is about 20%. The radial distribution of the atomic percentage of bromine around anode copper is given and has been explained qualitatively.
