When solids are exposed to intense laser fields whose forces are comparable to the binding
forces of valence electrons in crystals, nonlinear optics of solids advances to the …

Intense ultrashort light pulses comprising merely a few wave cycles became routinely
available by the turn of the millennium. The technologies underlying their production and …

The long-standing scientific quest of real-time tracing electronic motion and dynamics in all
states of matter has been remarkably benefited by the development of intense laser-based …

We report time-resolved electroabsorption of a weak probe in a 500 μ m thick zinc-oxide
crystal in the presence of a strong midinfrared pump in the tunneling limit. We observe a …

High harmonic generation (HHG) spectroscopy has opened up a new frontier in ultrafast
science, where electronic dynamics can be measured on an attosecond time scale. The …

We present a 9 GW peak power, three-cycle, 2.2 μm optical parametric chirped-pulse
amplification source with 1.5% rms energy and 150 mrad carrier envelope phase …

We present experimental observations and corresponding numerical simulations illustrating
the difference-frequency generation of mid-infrared radiation using few-cycle near-infrared …

We have demonstrated efficient generation of high beam quality, high-energy and
broadband tunable femtosecond mid-infrared pulses using a three-stage collinear optical …

We present a harmonic generation experiment using liquid H_2O and D_2O interrogated by
a mid-infrared, 3.66 μm, laser at a maximum intensity of 8x10^ 13 W/cm^ 2. The unique …

We numerically study the filamentation of ultrashort laser pulses at 2 μm carrier wavelength
in noble gases (argon, xenon) and in air. Compared with filamentation in the near-visible …
