ABSTRACT:
Chirped Bragg gratings are used both for stretching and compressing of ultrashort optical pulses in a chirped pulse amplification system, so that even femtosecond pulses can be stretched and recompressed back to their initial shape and duration. When used in chirped pulse amplification systems instead of bulk diffraction grating stretchers and compressors, Bragg gratings offer unprecedented compactness, robustness and system efficiency.
