Abstract
Production of reflection relief holograms with asymmetric groove shape by two different. optical schemes is investigated. First optical scheme which was used is counterdirected. Second optical scheme is rionsymmetr-ic codirected. The holograms are made on photoresist CK17 type. It is shown that if spatial frequency of obtained holograms is corit. ant the hol ogram recorded i n a counter di rected scheme had experimental value of blaze wavelength about 220230 nm as calculated val ue of wavel ength was about 280 nm. The hol ograms recorded i n a codirected asymmetric scheme had experimental value of blaze wavel ength about 660-700 nm though the cal cul ated val ue was about 1560 rim. Diffraction efficiency of obtained holograms exceeded the value of 7O for natural light in both cases. 1 .
