Abstract
We propose a new all-fiber cascade picosecond pulse amplification scheme based on optical fibers with varying normal group velocity dispersion (GVD). Amplification is performed in the fiber sections with exponential growth of the normal dispersion. Amplification sections are altered by the sections of passive fibers with the decreasing normal GVD. The pulse chirp in dispersion decreasing fibers can be adjusted by the increment of dispersion variation which would allow to control the spectral bandwidth of the pulse to keep it within an amplification band.
