Advanced Techniques for Improving Laser Optical Surfaces

Abstract

At Raytheon Company, Dr. C.B. Willingham was the principal investigator of the project. R. Cosgro and F. Taylor performed the experimental polishing work. Optical property measurements were made by Dr. T. Kohane, M. Schapira and T. Varitimos. Scanning electron microscopy was performed by Dr. O. Guentert and X-ray diffraction analysis by D. Howe. Ion beam polishing experiments were performed by Mr. John Gale at Ion Optics, Inc., Winchester Mass. and at Raytheon by C. Dunnrowicz. The zinc selenide polishing effort carried out at Itek Corporation, Lexington, .Mass. was directed by W.P. Barnes. Laser damage experiments were conducted at the Air Force Cambridge Research Laboratories with the assistance of Mr. R. Bradbury. Others contributing to the project included Drs. P.A. Miles, D.W. Readey and R. T. Newberg. This report has been given an internal number of S-1856.
