title: Vector-dispersion compensation and pulse pedestal cancellation in a femtosecond nonlinear amplification fiber laser system.
abstract: We report on a femtosecond nonlinear amplification fiber laser system using a vector-dispersion compressor, which consists of a transmission grating pair and multipass cell based Gires-Tournois interferometer mirrors. The mirror is designed with nearly zero group-delay dispersion and large negative third-order dispersion. As a result, the third-order dispersion of the compressor can be adjusted independently to compensate the nonlinear phase shift of amplified pulses to reduce the pulse pedestal. With this scheme, the system outputs 44  fs laser pulses with little wing at 26.6  W output average power and 531  nJ pulse energy, corresponding to 10.8  MW peak power.
