The exploitation of nonlinear phase shifts ( Φ N L ) 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 Φ N L is a challenging multivariable problem. We introduce an approximate theoretical model that is valid as long as the Φ N L 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.
