Guiding Effect

We demonstrate that short laser pulse self-guiding over distances of many Rayleigh lengths can be achieved in the absence of any focusing nonlinearity as a result of trapping of a leaking wave in a plasma channel produced by field-induced ionization in the saturation regime. A detailed computational study of the new self-guiding effect in both cases of comparatively long laser pulses, when the traditional approximation of the slowly varying complex amplitude is valid, and of high intense ultrashort laser pulses comprising only few field cycles have been performed.

Ultrashort Laser

The propagation of ultrashort laser pulses into a microstructured fiber having a large nonlinear coefficient is found to give rise to various nonlinear phenomena. By using an input wavelength in the range 1300–1550 nm, the observed output spectrum presents, besides supercontinuum generation, sharp lines due to third-harmonic generation and four-wave mixing. When the input wavelength is around 800 nm, close to the zero-dispersion wavelength, the solitonic propagation is accompanied by a very intense and narrow-band emission in the blue spectral region.

Field Strengths

Abstract Strong terahertz (THz) electric and magnetic transients open up new horizons in science and applications. We review the most promising way of achieving sub-cycle THz pulses with extreme field strengths. During the nonlinear propagation of two-color mid-infrared and far-infrared ultrashort laser pulses, long, and thick plasma strings are produced, where strong photocurrents result in intense THz transients. The corresponding THz electric and magnetic field strengths can potentially reach the gigavolt per centimeter and kilotesla levels, respectively. The intensities of these THz fields enable extreme nonlinear optics and relativistic physics. We offer a comprehensive review, starting from the microscopic physical processes of light-matter interactions with mid-infrared and far-infrared ultrashort laser pulses, the theoretical and numerical advances in the nonlinear propagation of these laser fields, and the most important experimental demonstrations to date.
