Abstract
Advanced laser systems with high power, good beam quality and strong stability are always the research objectives. Volume Bragg diffractive elements recorded in photo-thermo-refractive glass have become one of the keys to the advanced laser technology development owing to their excellent optical property and diffractive ability. A detailed introduction to the applications and principles in the advanced laser technology with volume Bragg elements of different structures, including near-field filtering, spectral combining, semiconductor external-cavity spectral stabilization and chirped pulse broadening and compression, is presented.
