摘要：

The exploitation of nonlinear phase shifts (Phi(NL)) in chirped-pulse fiber amplifiers has been demonstrated recently. Systematic optimization of the performance of a femtosecond-pulse fiber amplifier in the presence of substantial Phi(NL) is a challenging multivariable problem. We introduce an approximate theoretical model that is valid as long as the Phi(NL) is not so large that the spectrum changes substantially. The model allows an arbitrary chirped-pulse amplification system to be described by a set of four universal curves. These reveal the scaling of performance and allow determination of the optimal values of residual group-velocity dispersion and third-order dispersion for a given pulse duration and energy.
