Abstract

Techniques for evaluating the diffraction efficiency of infrared gratings have been developed and utilized at the Air Force Weapons Laboratory as part of the high energy laser component development effort. The key to accurate infrared diffraction efficiency measure-ments is good angular alignment and linear detection. The AFWL OMiGA diffraction code has proven to be very useful in determining the expected efficiencies of various coated and uncoated grating designs. Successful use of this program requires a good method of determining the groove profile of the grating. One successful method that we have developed will be discussed.
