Mutual compensation of higher-order dispersion in chirped pulse amplification system with regenerative amplifier

In this paper, based on ray tracing, the approach of mutual compensation that introduced properly the negative third-order dispersion to balance the higher-order dispersion in the chirped pulse amplification (CPA) system with regenerative amplifier is presented. A shorter pulse with near-transform-limitation can be generated by this method than by the conventional approach that zeros the second- and the third-order dispersion successively in the CPA system.
