Abstract: The surface of a recording medium was illuminated with a nonuniformity of less than 10% using second-harmonic radiation from a neodymium laser and the characteristic features of the illumination were considered. A laboratory technology was developed for fabricating 10-cm diameter holographic optical elements. This was based on optimizing the characteristics of a dichromated gelatin film, while obtaining a surface relief by recording with a 0.53-μm radiation pulse. The high image quality formed by a holographic optical element, with a low light scattering level, provides grounds for predicting extensive use of solid-state lasers in the fabrication of holographic optical elements.
