The optical performance of antireflection coatings on alkaline earth fluoride window materials at DF chemical laser wavelengths is presented. Reported coating absorption losses are less than 0.01% per surface. Those material properties that are important for this application are discussed, and theoretical coating designs are compared with experimental results.
