Paper Abstract

Solutions to several problems in relief grating holographic fabrication are presented. (1) The requirements for high-spectral selectivity and for a low stray light level are contradictory, but this problem can be solved by a compromise in the recording arrangement. (2) A real-time groove-depth control is proposed that ensures the fast and effective determination of the accurate exposing and developing conditions. (3) The necessity of baking the photoresistive grating before its metalization is clearly demonstrated by experiment.
