Abstract

The purpose of this work is to screen candidate materials for use in the iodine laser which operates at 1.315 μm. The results presented here are the effective optical absorption coefficient, β^eff, measured by laser rate calorimetry using a Quantronix Nd:YAG laser modified to operate at 1.319 μm. Here we extend the measurements reported last year to new materials. These include MgF², MgO, Kigre Q-98 phosphate glass, YAG (Y³Al⁵O¹²), water clear ZnS, CdTe, Schott IRG-N6 CaAl silicate, IRG-7 lead silicate, IRG-9 fluorophosphate glasses, and Hughes HBL glass. Spectral transmission scans using a Beckman 5270 and a Perkin-Elmer 180 spectrophotometer are presented for some of the less common materials. We also take this opportunity to report remeasured absorption values for data reported last year.
