Abstract

Because the dissociated bromine in CuBr lasers has serious effects on the lifetime of CuBr lasers and the stability of the discharged plasma, it is important in long-lived sealed-off CuBr lasers. The adsorption of bromine on the surface of the copper around the electrodes was measured by a transmission electron microscope and an x-ray energy dispersive spectrometer. It was found that the bromine dissociated from the CuBr molecule by collision in the laser discharge plasma is a 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 the copper anode is given and has been explained qualitatively.
