We propose two methods for ultrashort pulse parametric visible-to-infrared frequency conversion, that are directly applied to extend the tuning range of a commercial Ti:sapphire laser-noncollinear optical parametric amplifier system. The first method is based on broadband noncollinear four-wave optical parametric amplification in fused silica, and the second is based on cascaded three-wave parametric interaction in a single BBO crystal. The proof-of-principle experiments demonstrate generation of sub-30-fs, ∼20 µJ pulses, broadly tunable across the infrared (1-3 µm) spectral range.

“…A simple theory describing four-photon parametric interactions in condensed media along with phase-matching considerations is presented in [31]. In this section we extend this theory and develop an analytical model of the four-wave parametric amplification in a transparent isotropic bulk medium with account for the self-and cross-phase modulation experienced by the intense pump and weak signal and idler waves, respectively, in the plane and monochromatic wave approximation.…”

We report on efficient generation of the ultrashort ultraviolet light pulses by means of phase-matched four-wave optical parametric amplification and four-wave difference frequency mixing in UV-transparent solids with cubic nonlinearity. Broadband four-wave optical parametric amplification around 330 nm is investigated theoretically and demonstrated experimentally in optically isotropic materials, such as fused silica and CaF2 crystals. The results suggest that powerful broadband ultraviolet pulses as short as 7.5 fs (in the transform limit) could be amplified in the field of milijoule 1-ps visible pulses. Efficient generation of 1-ps pulses at the 3rd (351 nm), 5th (211 nm), and, in particular, 6th (176 nm) harmonics of the Nd:glass laser is experimentally demonstrated through non-collinearly phase-matched four-wave difference-frequency mixing in fused silica, CaF2 and MgF2 crystals.

“…Experimental evidence is reported of this remarkable behavior in soliton array generation by OPA in a Kerr planar waveguide. Note also that, since its first observation in 1996 [11], very few studies have focused on the spatial case of four-wave mixing in Kerr media [12][13][14][15][16], whereas temporal four-wave mixing or modulation instability processes have extensively been investigated in the context of fiber optics [17].…”

International audienceIn a way analogous to a light pulse that can be optically delayed via slow light propagation in Kerr-type nonlinear media, we theoretically demonstrate that beam steering and spatial walk-off compensation can be achieved in noncollinear optical parametric amplification. We identify this effect as a result of the quadratic phase shift induced by parametric amplification that leads to the cancellation of the spatial walk-off and collinear propagation of all beams though they have different wavevectors. Experimental evidence is reported of a soliton array steering in a Kerr slab waveguide
