We derive a time-domain mean-field equation to model the full temporal and spectral
dynamics of light in singly resonant cavity-enhanced second-harmonic generation systems …

We report on the generation of ultrabroadband supercontinuum (SC) by filamentation of two
optical-cycle, carrier-envelope phase-stable pulses at 2 μm in fused silica, sapphire, CaF_2 …

We report on even and odd harmonics-enhanced supercontinuum generation in
polycrystalline ZnS and ZnSe samples, as pumped by femtosecond mid-infrared pulses. We …

We investigate the properties of the recently introduced time-diffracting (TD) beams in free
space. They are shown to be paraxial and quasimonochromatic realizations of …

Bright and broadband coherent mid-IR radiation is important for exciting and probing
molecular vibrations. Using cascaded nonlinearities in conventional quadratic nonlinear …

We experimentally study filamentation and supercontinuum generation in a birefringent
medium [beta-barium borate (β-BBO) crystal] pumped by intense 90 fs, 1.8 μm laser pulses …

We experimentally investigate filamentation and supercontinuum generation in a
birefringent medium (BBO crystal), in the self-focusing regime where intrinsic cubic …

We study the nonlinear optical properties of lithium niobate (LiNbO_3) nanowires (NWs)
fabricated by a top-down ion beam enhanced etching method. First, we demonstrate …

We report an experimental and numerical investigation of third-and fifth-harmonic
generation in a CaF 2 crystal with 20 fs (three-optical-cycle), 2 μ m driving pulses. The …

We show that a temporal soliton can induce resonant radiation by three-wave mixing
nonlinearities. This constitutes a new class of resonant radiation whose spectral positions …
