Abstract
The disclosed molecular excimer laser discharge tube employs a transverse ectrical discharge with a UV preionization. The discharge tube is made of pure quartz with two optical quality windows fused onto the two ends. The mechanical support and electrical feedthrough for the profiled molybdenum cathodes are provided by commercially available quartz molybdenum cup seals. The anode is made of perforated molybdenum sheet and is supported by slots formed in quartz plates. The preionization for the main discharge is generated from 'V' cuts provided in a molybdenum ribbon sealed in a quartz tube.
