| Abstract: | This paper presents the spectral emission and saturation properties of a Lumilass G9 fluorescence glass excited using a 157 nm laser emitting ∼10 ns duration pulses. This fluorescence glass can be applied in conjunction with a CCD array for beam profiling and divergence measurements. This method can also be used for deriving information on the spatial coherence function of the F2 laser. This constitutes one of the major contributions of the paper and is also discussed. |
