“…The experiment described in [17] can be interpreted similarly with a quasi-phase matching that is satisfied at 895 nm and 1235 nm, while the numerical simulation shows the initial appearance of sidebands at these wavelengths, with a progressive shift towards a greater wavelength separation from the pump upon propagation. We believe this shift to be due to the decrease of peak power caused by the non-negligible group-velocity dispersion of argon at a pressure of 4 bar.…”

“…In contrast, the modified 2D model proposed here typically takes a few tens of seconds to run on such a machine. The experiments are described in [16,17]. The model is implemented without any adjustable parameters based on the information provided in these references.…”

“…2 (top) shows that the nonlinearity induces slow and relatively low amplitude oscillations on the beam size, in addition to the roundtrip modulation caused by propagation in the MPC. The second experiment we use to benchmark the model is reported in [17], and corresponds to the highest average power ever reported in an MPC-based nonlinear compression setup. Input pulses of 1.1 mJ at 500 kHz repetition rate are compressed from 590 fs down to 30 fs in a 794 mm-long MPC made of 400 mm radius of curvature mirrors filled with argon at 4 bar.…”

“…We compare its results both to a full 4D model and to the very simple 2D model described in [11], showing that the level of physical description adopted is ideal for the particular problem of propagation in MPCs. In a second part, we apply the model to reproduce the experimental data obtained in high-energy gas-filled MPC experiments that use near concentric configurations [16,17]. In this case, the small beam size and large divergence at the MPC waist makes 4D simulations particularly computationally intensive, underlining the usefulness of our model.…”

We describe a nonlinear propagation model based on a generalized Schrödinger equation in the time domain coupled to Gaussian beam evolution through ABCD matrices that account for Kerr lensing in the spatial domain. This model is well suited to simulate propagation in mildly nonlinear systems such as multipass cells for temporal compression. It is validated against both a full (x,y,z,t) numerical model and recently reported experimental results in multipass cells, with excellent agreement. It also allows us to identify the physical mechanism for the recently reported parasitic appearance of spectral content in the 700-950 nm range in argon-filled multipass cells that are used to compress pulses at 1030 nm. We think this is due to a quasi-phase matched degenerate four-wave mixing process. This process could be used in the future to perform wavelength conversion as is already done in fibers and capillaries.

“…This results in a record compression factor of ~32 at an excellent overall transmission of 95.7%. With this technique, the highest average power of 530 W was achieved compressing 590 fs 1.1 mJ pulses to 30 fs (20 times compression) at 500 kHz repetition rate in a 44-pass cell with a throughput of 96% [68].…”

Contemporary ultrafast science requires reliable sources of high-energy few-cycle light pulses. Currently two methods are capable of generating such pulses: post compression of short laser pulses and optical parametric chirped-pulse amplification (OPCPA). Here we give a comprehensive overview on the post-compression technology based on optical Kerr-effect or ionization, with particular emphasis on energy and power scaling. Relevant types of post compression techniques are discussed including free propagation in bulk materials, multiple-plate continuum generation, multi-pass cells, filaments, photonic-crystal fibers, hollow-core fibers and self-compression techniques. We provide a short theoretical overview of the physics as well as an in-depth description of existing experimental realizations of post compression, especially those that can provide few-cycle pulse duration with mJ-scale pulse energy. The achieved experimental performances of these methods are compared in terms of important figures of merit such as pulse energy, pulse duration, peak power and average power. We give some perspectives at the end to emphasize the expected future trends of this technology.

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.
