Atmospheric pressure operation of an electron beam excited KrF laser using Kr/F2mixtures

摘要

Atmospheric pressure operation of a KrF laser pumped by 50hyphen;ns electron beams was experimentally investigated. For a 1hyphen;atm mixture of Kr and F2without diluent, a specific output energy of 4.2 J/1 was obtained at 1.7hyphen;MW/cm3excitation rate. Under this condition the intrinsic efficiency was about 5percnt; (6percnt; was maximum at 20percnt; Kr in argon diluent) which was comparable to that from 1hyphen;atm normal (10percnt; Kr) mixtures.
