An experimental examination of the lifetime limiting processes in a whole-heated sealed-off CuBr laser is performed. The influence of the CuBr expenditure, the pollution of the laser windows, the recombination processes and the change of the plasma composition, especially the bromine concentration increase is investigated. Considering the experimental results a sealed-off CuBr laser of not less than 500 h of operation is designed.
