Transient absorption measurements are performed on e-beam excited KrF under lasing and nonlasing conditions for 10% Kr (Ar diluent) and 99.6% Kr gas mixtures. The intracavity flux is varied by changing the output mirror reflectivity. The deposition rate for this experiment is {approx}396 kW/cm{sup 3}. For the 10% Kr and Kr-rich mixtures, the small signal absorption at 248.4 nm is 0.76%/cm and 1.25%/cm, respectively; while the nonsaturable absorption in 0.62%/cm and 0.90%/cm, respectively. A flux loading of {approx}1.5 MW/cm{sup 2} is needed to achieve nearly complete saturation of the saturable absorption.
