Optical field waveforms with an ultrabroad spectrum and a tailored phase are shown to enable selective excitation, coherent control, and attosecond spectrochronography of electron subshells in many-electron atomic systems. Analysis of the evolution o

Combined optical nonlinearity of bound and free electrons in a fast-ionizing medium driven by ultrashort, mid-infrared (mid-IR) pulses gives rise to a vast variety of ultrafast nonlinear-optical scenarios, producing bright, broadband radiation in spe

We identify physical scenarios whereby high-peak-power subcycle attosecond field waveforms can be synthesized by coherently combining a multibeam high-order harmonic output generated by a laser driver consisting of a pair of few-cycle pulses with dif

We present experimental observation of optical signals induced by tunnel ionization and a theoretical model for the generation of new optical and THz frequencies in media ionized by a high intensity laser field. The emergence of sidebands is treated

By numerically solving the generalized nonlinear Schrodinger equation, we provide a comparative analysis of spectral and temporal transformations of pico and femtosecond laser pulses in a guided mode with a generic dispersion profile typical of a pho

We experimentally demonstrate efficient controlled parametric frequency conversion of femtosecond laser pulses through cross-phase-modulation-induced instability in the presence of a copropagating pump field in a fused silica photonic-crystal fiber.

A photonic-crystal fiber that supports only a few guided modes is shown to allow the generation of a spectrally isolated wavelength-tunable hollow beam, which is ideally suited for optical trapping and laser tweezing.
