Chirped volume Bragg gratings (CVBG)     

Reflecting chirped volume Bragg gratings (CVBGs) recorded in PTR glasses, with a gradually variable period in the beam propagation direction provide stretching and recompression of chirped pulse amplification (CPA) system. The CVBG not only has the characteristics of high damage threshold, but compact size, insensitive to light path and easy to integration, thus for high power short pulse fiber laser has played a tremendous role in promoting industrial development. The CVBG samples with customized parameters have been developed. Welcome to customize according to application requirements.
