Mücke,Audrius Pugzlys,Andrius Baltuška,Bonggu Shim,Samuel E. Schrauth,Alexander L. Gaeta,Carlos Hernandez-Garcia,Luis Plaja,Andreas Becker,Agnieszka Jaron-Becker,Margaret M. Murnane,Henry C. Kapteyn +19 more
TL;DR: By guiding a mid-infrared femtosecond laser in a high-pressure gas, ultrahigh harmonics can be generated that emerge as a bright supercontinuum that spans the entire electromagnetic spectrum from the ultraviolet to more than 1.6 kilo–electron volts, allowing, in principle, the generation of pulses as short as 2.5 attoseconds.

90 GW peak power few-cycle mid-infrared pulses from an optical parametric amplifier
Giedrius Andriukaitis,T. Balčiūnas,Skirmantas Alisauskas,Audrius Pugžlys,Andrius Baltuška,Tenio Popmintchev,Ming-Chang Chen,Margaret M. Murnane,Henry C. Kapteyn +8 more
TL;DR: A compact 20 Hz repetition-rate mid-IR OPCPA system operating at a central wavelength of 3900 nm with the tail-to-tail spectrum extending over 600 nm and delivering 8 mJ pulses that are compressed to 83 fs opens a range of unprecedented opportunities for tabletop ultrafast science.

TL;DR: In this paper, an experimental proof and full characterization of laser generation in molecular nitrogen in an argon-nitrogen gas mixture remotely excited at a distance above 2 m in a femtosecond laser filament was reported.

TL;DR: This work demonstrates filamentation of ultrashort mid-infrared pulses in the atmosphere for the first time and shows that, with the spectrum of a femtosecond laser driver centered at 3.9 μm, radiation energies above 20 mJ and peak powers in excess of 200 GW can be transmitted through the atmosphere in a single filament.
