Abstract

Optical absorption values of uncoated calcium fluoride and fused silica substrates were measured at 351 nm using the 3-slope laser calorimetry technique. In addition, various substrate cleaning techniques were tried in order to lower the absorption, and to assess the contribution of surface contaminants to the total absorption.
