Temporal Pulse Shaping Technique for Self-Phase Modulation Tailoring

Self-phase modulation (SPM) of gaussian-like pulses induces spectral broadening. This nonlinear effect enables the implementation of post-compression techniques, using a multipass cell (MPC) [1] for instance. Coupled to temporally shaped input pulse, SPM can lead to other applications such as spectral tunability as shown for low energy pulses in [2]. Here, we report a deterministic spectral phase-only pulse-shaping technique that is a generalized version of the method presented in [3]. It introduces a nonlinear chirp to generate arbitray shapes in the time domain. We illustrate the technique with the spectral tunability application for high energy pulses.
