“…Thus, DPNLC is an extremely powerful extension to easily scale the performance of pre-built MPC-based nonlinear compression stages without requiring a complete rebuilding and, when designing an MPC from scratch, it allows significant reduction of cost and size of the setup. In future, we will demonstrate the experimental applicability of this technique, extend it to more pulse replicas, thus further increasing the MPC-supported output energy, and also transfer it to a setup for few-cycle pulse compression [20].…”

The pulse-energy and peak-power limitations of a gas-filled multipass cell (MPC) for nonlinear pulse compression are surpassed by applying a burst of four temporally separated pulses instead of a single one. The burst is generated by two birefringent crystals and contains 1 m J of energy per pulse replica. It is then spectrally broadened in an Argon-filled MPC and recombined into a single pulse by a second set of birefringent crystals. The combined pulse is compressed by chirped mirrors to a pulse duration of 32 f s and a pulse energy of 3.4 m J . An excellent passive stability and a high system efficiency of > 90% are reached. Using the 4-pulse burst, the overall output energy supported by the MPC is doubled in comparison to single-pulse operation.

“…Replacing tantalum pentoxide by titania as high index material of the quarter-wave stack mirrors would enable the generation of about 20 fs pulses. By using enhanced metallic mirrors, even few-cycle pulses were demonstrated [14,37]. Conventional anti-reflection coatings would lead to clearly lower MPC transmissions if larger bandwidths with the same number of roundtrips are targeted.…”

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.

“…However, as the pulse energy and beam size on the cell mirrors increase, the benefits of using single, large diameter curved mirrors decrease compared to the use of multiple small mirrors at each reflection, a more cost-effective solution. High energy MPCs are being designed along this idea, [32,33] that also makes the spot pattern at each end of the MPC arbitrary, resulting in possibly more compact setups in the transverse direction with respect to light propagation.…”

“…Another method to reach few‐cycle pulse durations at the output of MPC‐based compressors with a high efficiency consists in designing a second MPC compression stage using enhanced metallic mirrors with a small number of reflections. [ 32 ] Although the overall throughput could not be measured because only a fraction of the output power was sent to the chirped mirror compression system, the second MPC has a transmission of 82%, which is comparable to a capillary setup. Another interesting feature of this work is that the MPC is composed of multiple small curved mirrors instead of a single large‐diameter mirror.…”

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.
