In the last decade, there has been a proliferation of laser sources for time-and angle-
resolved photoemission spectroscopy (TR-ARPES), building on the proven capability of this …

The advent of chirped-pulse amplification in the 1980s and femtosecond Ti: sapphire lasers
in the 1990s enabled transformative advances in intense laser–matter interaction physics …

Vertical heterostructures of transition metal dichalcogenides (TMDs) host interlayer excitons
with electrons and holes residing in different layers. With respect to their intralayer …

We present an experimental investigation of supercontinuum generation in potassium
gadolinium tungstate (KGW) and yttrium vanadate (YVO_4) crystals pumped with 210 fs …

We report on high-energy, few-cycle pulse generation in the long-wave infrared spectral
region via difference-frequency generation (DFG) in GaSe and AgGaSe_2 nonlinear …

Copper chalcogenides are materials characterized by intrinsic doping properties, allowing
them to display high carrier concentrations due to their defect‐heavy structures, independent …

A 2.6-fold spectral broadening of mid-infrared femtosecond µJ-level pulses has been
achieved using an unfolded multi-pass configuration of germanium plates and zinc selenide …

We introduce a broadband tunable femtosecond laser source in the long-wave infrared
(LWIR) band, covering the range of 5–13.5 μm, based on the integration of optical …

In this work we present a compact two-stage optical parametric amplifier (OPA) pumped at
degeneracy by the fundamental of a Yb: KGW laser system. The output pulses span from 1.7 …

We demonstrate a widely tunable, ultrafast optical parametric amplifier (OPA) based on
cascaded noncollinear-collinear KTiOAsO 4 (KTA) crystals seeded by a white light …
