Abstract
A method for amplifying an ultrashort laser pulse includes: a) stretching the ultrashort laser pulse in time, b) amplifying the time-stretched laser pulse, c) compressing the amplified time-stretched laser pulse, with at least one gain phase contribution selected from a group consisting of a gain dynamics phase contribution of the laser pulse that emerges as a change in a nonlinear phase on account of gain dynamics in step b), a gain bandwidth phase contribution of the laser pulse that emerges as a change in the nonlinear phase on account of a gain bandwidth in step b), and a combination thereof, being compensated by virtue of d) an additional phase contribution being imparted on the laser pulse prior to step c) and/or e) a spectrum of the laser pulse being changed, in such a way that the at least one gain phase contribution is compensated after step c).
