TL;DR: Efficient sub-cycle THz pulse generation by using two-color midinfrared femtosecond laser filaments in ambient air using affordable table-top laser systems is experimentally demonstrated.

TL;DR: In the mid-infrared wavelength range that is important for scaling the ponderomotive energy in strong-field interactions, a simple energy-efficient and scalable soliton-like pulse compression in a mm-long yttrium aluminium garnet crystal with no additional dispersion management is demonstrated.

TL;DR: In this paper, a single-filament regime with peak powers as high as 0.3 TW was achieved in a truly single-mode, almost diffraction-limited 35fs output at a central wavelength of 4μm.

TL;DR: These are the first results of laser plasma wakefield acceleration driven by ultrashort mid-infrared (IR) laser pulses, which enable near- and above-critical density interactions with moderate-density gas jets.

TL;DR: In this paper, the authors identify and experimentally demonstrate a physical scenario whereby high-peak-power mid-infrared (mid-IR) pulses can be compressed as a part of their free-beam spatiotemporal evolution within the regions of anomalous dispersion in air to yield few-cycle subterawatt field waveforms.
