Abstract:

The increasing interest and importance of chemical lasers has led to a demand for materials studies at DF and HF chemical laser frequencies. The primary objective of this research program has been to investigate the optical absorption in a wide variety of low loss materials suitable for use as windows on high-powered chemical lasers. In order to accomplish this objective, the small optical absorption in a number of different state-of-the-art samples was measured using DF-HF chemical laser calorimetric techniques. These measurements, combined with a correlative study of surface absorption, have been compiled in order to bring together in a systematic fashion all the absorption data accumulated during the contract period. Such a compilation of data enables one to easily identify those materials which, up to the present time, hold the greatest promise, in terms of service and reliability, as chemical laser windows.
