Abstract

This paper discusses the design and performance of CuBr lasers. It is demonstrated that a sealed off CuBr laser tube of 1000 h operation is allready realizable. Investigation of the output parameters in laser tubes with a limited discharge zone shows that the output power and efficiency increase 2 times when a small amount of hydrogen is added to the neon buffer gas. We obtained from a typical CuBr laser tube with an electrode spacing of 50 cm and an i.d. of 2 cm an average output power as high as 20 W with a plug-in HV efficiency of 1.5%. At a repetition frequency of 16 kHz this implies 8 mJ/l laser energy extraction from unit active volume or 0.13 W/cm³.
