Instantaneous Frequency representation used for CPA laser simulation

Oksenhendler, T.; Bock, S.; Schramm, U.

We present a novel intuitive graphical method for the simulation of non-linear effects on stretched pulses characterized by a large time-bandwidth product. By way of example, it allows precise determination of effects occurring in CPA (chirped pulse amplification) laser chains, such as the pre-pulse generation by the non-linear Kerr effect. This method is not limited to first order dispersion and can handle all resulting distortions of the generated pre-pulse.

Keywords: ultra-short laser pulses; laser pulse contrast; high-power laser
