Abstract:

Among most serious disadvantage limiting the service life of CuBr vapor laser tubes is poisoning of a hydrogen reservoir with gases produced in a laser tube during operation. A new design of a hydrogen reservoir using selective diaphragms permeable only for hydrogen and thus eliminating the possibility of poisoning with various gases was developed. This design provides for and maintains optimal hydrogen pressure during the entire service life of a laser head.
