This course explains basic principles and applications of volume Bragg gratings (VBGs) that are holographic optical elements recorded in volume of photo-thermo-refractive optical glass. These elements enable dramatic increase of brightness of lasers and resolution of spectral analyzers. The goal of the course is to describe features of photosensitive optical glass , properties of VBGs, principles of gratings modeling and design, main types of optical components based on VBGs, and amazing results of their use in lasers and photonic devices. People who want to bring lasers and photonic devices to a new level will benefit from taking this course.
