Paper Abstract

The relevant characteristics of a 248 nm line-narrowed excimer laser have been measured. The laser's spectral width is 1.6 pm FWHM and its coherence length is 38 mm. The effects of this line narrowing on the optical components in illuminator systems have been studied. The results from several light pipe systems and a diffuser plate system are presented. The effects of external cavity collimation on the GCA-TROPEL BOLD illuminator are also presented.
