TL;DR: It is shown that ultrabroadband terahertz pulses can simultaneously trace the ultrafast evolution of coexisting lattice and electronic orders and demonstrates the sort of profound insight that disentangling strongly coupled components of order parameters in the time domain may provide for the understanding of a broad class of phase transitions.

TL;DR: In this article, phase-matched difference frequency mixing within the broad spectrum of sub-10 fs pulses in LiIO3 was proposed to generate ultrabroadband pulses spanning the 50-130 THz frequency range via phase-matching frequency mixing, and the broad applicability of this scheme was demonstrated with 9-fs pulses from a Ti:sapphire oscillator and with 7-fs amplified pulses from hollow fiber compressor as pump sources.

TL;DR: A tunable pump, high-harmonic probe laser source with a 3D momentum imaging technique to map photoemitted electrons from monolayer WS2 provides momentum-, energy- and time-resolved access to excited states on an ultrafast time scale.

TL;DR: In this paper, a terahertz emitter based on the lateral photo-Dember effect was shown to efficiently generate terAhertz radiation with a peak frequency of 0.7 THz and an electric field amplitude up to 5 V/cm when excited by 90 fs pulses centered at 1.55μm.

TL;DR: In this article, femtosecond photoactivation of a switch element inside the cavity disrupts the deep-strong coupling more than an order of magnitude faster than the oscillation cycle of light.
