Intracavity flux dependent absorption in E-beam pumped KrF
Abstract
Transient absorption measurements are performed on e-beam-excited KrF under lasing and nonlasing conditions for 10-percent Kr (Ar-diluent) and 99.6-percent Kr gas mixtures. The intracavity flux is varied by changing the output-mirror reflectivity. The deposition rate for this experiment is about 386 kW/cu cm. For the 10-percent Kr and Kr-rich mixtures, the small signal absorption at 248.4 nm is 0.76 percent/cm and 1.25 percent/cm, respectively; while the nonsaturable absorption is 0.62 percent/cm and 0.90 percent/cm, respectively. A flux loading of about 1.5 MW/sq cm is needed to achieve nearly complete saturation of the saturable absorption.
