“…This means the peak power of the pulse will be severely diminished. For the case of negative input chirp, the spectrum initially becomes narrower at lower B-integrals as shown in [39], but eventually also results in spectral broadening. Note that the white part on the left hand side of the two plots do not contain data, as the compression factor is always greater than 1 when the pulse is compressing.…”

Post-compression of ultra-short laser pulses via selfphase modulation is routinely employed for the generation of laser pulses with optical bandwidths reaching far beyond the laser gain limitations. While high compression factors can be routinely achieved, the compressed pulses typically suffer from temporal quality degradation. We numerically and experimentally analyze the deterioration of different measures of temporal quality with increasing compression factor and show how appropriate dispersion management and cascading of the post-compression process can be employed to limit the impact of this effect. The demonstrated saturation of pulse quality degradation at large compression factors puts novel femtosecond laser architectures based on post-compressed pico-or even nanosecond laser systems in sight.

“…Another recent example of a nonlinear process observed in an MPC is spectral compression. [ 77 ] This phenomenon is observed when negatively chirped pulses are subject to SPM. The nonlinear phase accumulated upon propagation shifts extreme spectral components toward the center of the spectrum, thereby canceling the initial chirp and generating almost Fourier‐transform limited pulses with an unchanged duration.…”

The fundamental principles and experimental implementations of multipass cells used as a platform for nonlinear optics are reviewed. Embedding a nonlinear medium in a multipass cell allows for a distribution of the nonlinearity over large interaction distances, while the beam goes through multiple foci, conferring on the beam a robustness with respect to spatio-spectral coupling effects. Most of the research so far has been focused on temporal compression based on self-phase modulation, with excellent performances especially in terms of energy scaling and throughput. However, other nonlinear phenomena and functions are being increasingly investigated, such as supercontinuum generation, spectral compression, or Raman scattering. Nonlinear optics experiments in multipass cells bear some similarities with the work done in optical fibers over several decades, while allowing straightforward energy scaling potential, and unlocking engineering possibilities through the design of the cell mirrors, geometry, and nonlinear medium.
