Abstract
High-intensity femtosecond laser pulses can be used to study laser-material interactions in a regime in which classical perturbative theories fail. Examples of nonlinear- optical phenomena not described by perturbative nonlinear optics include high- harmonic generation, supercontinuum generation, and ionization-induced spectral blue shifting. The last effect occurs when an intense femtosecond laser pulse propagates through a gas and field ionization causes a rapid increase in the electron density along the propagation path.
