We report on a high-power third-order dispersion managed amplification system that delivers 33-fs pulses of 93.5 W at a repetition rate of 55 MHz. A pair of grisms are used as the pre-chirper for optimizing the third order dispersion (TOD) to group velocity dispersion (GVD) ratio. Detail experiments show that the use of a grsim pre-chirper significantly enhances the quality of the compressed pulses. We demonstrate that the third order dispersion of both the amplifier and the compressor can be compensated for by the grisms. Furthermore, the nonlinear phase shift introduced by spectral asymmetry during amplification can be restrained. This type of scheme, applied in our experiment, can be used for further development of a high power laser with ultrashort pulse and wide spectrum.
