We report on the development of an ultrafast beam shaper capable of generating Bessel
beams of high cone angle that maintain a high intensity hot spot with subwavelength …

The versatility of optical parametric amplifiers makes them excellent sources for ultrashort
visible and infrared pulses that drive strong-field physics experiments. We extend four-wave …

Kerr instability can be exploited to amplify visible, near-infrared, and midinfrared ultrashort
pulses. We use the results of Kerr instability amplification theory to inform our simulations …

We experimentally demonstrate large, widely tunable gain using Kerr instability amplification
in MgO. By pumping the crystal near optical damage at 1.4× 10^ 13W/cm^ 2 by a …

Whereas the Kerr nonlinearity is well understood in the perturbative limit of nonlinear optics,
there is considerable discussion about its functional form and magnitude at extreme …

Kerr instability amplification can amplify over an octave of spectrum, a broad bandwdith
supporting few-cycle pulses. However, dispersion management in this regime is crucial to …

Light beams with broad spectral bandwidth are indispensable for the generation of ultrashort
light pulses. Here, the generation of broadband ultrashort light pulses from narrowband …

An important aspect of third-order optical nonlinearity is the intensity-dependent refractive
index, where the intensity of the light itself affects the refractive index. This nonlinear effect is …

Recently it was shown that Kerr instability via degenerate four-wave mixing can amplify
single-cycle Gaussian seed pulses from the visible to the deep infrared [Optica5, 271 …

When an intense laser beam interacts with matter, the Kerr nonlinearity results in self-
focusing. Above the critical intensity, self-focusing dominates pulse spreading through …
