Using sub-picosecond pulses, we report the first time observation of the formation of highly-stable multidimensional solitary states (MDSS) in molecular-filled hollow-core fibers. The MDSS have broadband red-shifted spectra with an uncommon negative quadratic spectral phase at output, originating from strong intermodal interactions. This approach paves the route to compress sub-picosecond Ytterbium laser systems to few-cycle pulse duration using a compact setup.

We report on the nonlinear temporal compression of mJ energy pulses from a Ti:Sa chirped pulse amplifier system in a multipass cell filled with argon. The pulses are compressed from 30 fs down to 5.6 fs, corresponding to approximately two optical cycles. The post-compressed beam exhibits excellent spatial quality and homogeneity. These results pave the way to robust and energy-scalable compression of Ti:Sa pulses down to the few-cycle regime.

We have experimentally demonstrated the post-compression of a long-wave infrared (9.2 µm) 150-GW peak power pulse from 2 ps to less than 500 fs using a combination of two optical materials with significantly different ratios of the nonlinear refractive index to the GVD coefficient. Such combination allows for optimization of the compression mechanism and promises a viable path to scaling peak powers to supra-terawatt levels.

Near-single-cycle pulses generated through post-compression on FAB1 laser at ATTOLAB-Orme facility

Generating energetic, few-cycle laser pulses with stabilized Carrier-Envelope Phase at high repetition rate constitutes a first step to access the ultra-fast dynamics underlying the interaction of matter with intense, ultrashort pulses in attosecond science or high field physics. We present here a post-compression stage delivering 3.8fs pulses with 2.5mJ coupled to a Ti: Sa based 1 kHz TW-class laser which can deliver 17.8fs pulses with 350mrad shot to shot CEP noise. This is the first step towards high energy few-cycle post-compression of the FAB laser at ATTOLAB-Orme.

Divided-pulse nonlinear compression in a multipass cell

We present the nonlinear pulse compression of an ytterbium-based 4-pulse burst in a gas-filled multipass cell as a scaling approach to increase the supported pulse energy and output peak power. The pulse division and passive recombination is based on birefringent crystals and enables an output pulse energy of 4.5 mJ at a pulse duration of 31 fs while more than doubling the energy limitations set by laser induced damage of the multipass cell mirrors. Overall, a good efficiency and temporal contrast are achieved.
