In this paper, a method of obtaining a blazed holographic grating by Fourier synthesis with a simple optical system is described. The optical path is adjusted by interferometry to improve the processing accuracy. The holographic blazed grating made in this experiment has a good serrated groove shape, The sparkling properties are remarkable, the + 1 diffraction efficiency exceeds 50%, and the efficiency is about 11 times higher than that of the -1 class.Finally, the problems of how to improve the diffraction efficiency, control the blaze wavelength and increase the scribing area are discussed.
