“…In contrast, the implementation of our method requires only off-the-shelf optics and enables strong spectral broadening by high B- [16] [17] [18] [25] [11] [12] integrals per pass. Therefore, our compression scheme is a compact alternative to more complex multi-stage setups [12,[19][20][21][22][23] and presents a highly attractive method to generate sub-50 fs pulses from a high-power picosecond laser.…”

As Ultrafast laser technology advances towards ever higher peak and average powers, generating sub-50 fs pulses from laser architectures that exhibit best power-scaling capabilities remains a major challenge. Here, we present a very compact and highly robust method to compress 1.24 ps pulses to 39 fs by means of only a single spectral broadening stage which neither requires vacuum parts nor custom-made optics. Our approach is based on the hybridization of the multi-plate continuum and the multi-pass cell spectral broadening techniques. Their combination leads to significantly higher spectral broadening factors in bulk material than what has been reported from either method alone. Moreover, our approach efficiently suppresses adverse features of single-pass bulk spectral broadening. We use a burst mode Yb:YAG laser emitting pulses with 80 MW peak power that are enhanced to more than 1 GW after post-compression.With only 0.19 % rms pulse-to-pulse energy fluctuations, the technique exhibits excellent stability. Furthermore, we have measured state-of-the-art spectral-spatial homogeneity and good beam quality of M 2 = 1.2 up to a spectral broadening factor of 30. Due to the method's simplicity, compactness and scalability, it is highly attractive for turning a high-power picosecond laser into an ultrafast light source that generates pulses of only a few tens of femtoseconds duration.

“…Cascading two bulk‐based nonlinear MPC compression stages has allowed compression of 460 fs pulses down to 22 fs, corresponding to a compression ratio of 21, at 15 µJ output pulse energy. [ 64 ] Since the transmission of each stage is high, it is possible to use three stages to compress 220 fs pulses down to 16 fs, while maintaining a throughput of 60%, at an output pulse energy of 2.6 µJ. [ 60 ] Dispersion management and design of the cell mirrors is increasingly challenging as the output pulse duration decreases, especially because these MPC mirrors must be highly reflective to preserve a high transmission.…”

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.

“…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.…”

Self-compression at 1 µm wavelength in all-bulk multi-pass geometry

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.
