“…Most of the achievements till today report on the compression to a duration not shorter than ~20 fs. The first successful attempt to reach the few-cycle regime with this technique utilized a cascade of two krypton-filled cells [69]. The first stage compressed the 2 mJ 1.2 ps pulses to 32 fs with 80% efficiency in 44 passes while the second stage could only be used at a reduced input energy of 0.8 mJ which then compressed the pulses to 13 fs in 12 passes at a throughput of only 46%.…”

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.

“…For a more detailed understanding of the temporal evolution of the pulse upon propagation through the MPC, simulations were carried out by numerically solving the nonlinear Schrödinger equation using an adaptive step-size implementation of the fourth-order Runge-Kutta in the interaction picture [21]. The simulations were performed on a one-dimensional grid spanning 16 ps in time and using 2 14 points, corresponding to a frequency resolution of 0.062 THz. To account for the discrete nature of the quasi-waveguide, each consecutive pass in the MPC was modeled by propagating the pulse through a 6.35-mm-long block of fused silica material and subsequently applying the dispersion curve of the MPC mirror to the pulse.…”

“…Lately, a new spectral broadening method relying on a waveguide-like periodic assembly consisting of focusing elements (concave dispersive mirrors) and nonlinear media was suggested and demonstrated [7][8][9][10]. Both, all-bulk and gasfilled geometries were successfully realized in high-average and peak power regimes, pushing the broadened spectrum to sub-10 fs Fourier limit and pulse durations to sub-30 fs in a highly robust and simple manner [11][12][13][14][15]. As one of the main advantages of this concept, the sign of the overall net dispersion and its profile including higher order dispersion terms can be readily engineered in the quasi-waveguide.…”

We present directly oscillator-driven self-compression inside an all-bulk Herriott-type multi-pass cell in the near-infrared spectral range. By utilizing precise dispersion management of the multi-pass cell mirrors, we achieve pulse compression from 300 fs down to 31 fs at 11 µJ pulse energy and 119 W average power with a total efficiency exceeding 85%. This corresponds to an increase in peak power by more than a factor of three and a temporal compression by almost a factor of ten in a single broadening stage without necessitating subsequent dispersive optics for temporal compression. The concept is scalable towards millijoule pulse energies and can be implemented in visible, near-infrared and infrared spectral ranges. Importantly, it paves a way towards exploiting Raman soliton self-frequency shifting, supercontinuum generation and other highly nonlinear effects at unprecedented high peak power and pulse energy levels.

“…These are expected to be experimentally confirmed soon. With that, the simple-to-implement and robust bulk broadening method becomes also increasingly competitive to gas-filled MPCs [5,6].…”
