Аннотация:Multioctave supercontinua provide a unique resource for ultrafast optical science, offering advanced tools fortime-resolved spectroscopy, frequency comb technologies, nonlinear microscopy, and lightwave engineering.The physical scenarios that enable the generation of such ultrabroadband wave packets are not always easyto describe in terms of standard models of ultrafast nonlinear optics; their properties are often unusual, andtheir nonlinear dynamics are much more than meets the eye. To adequately understand these new electrodynam-ics and to identify scenarios whereby multioctave supercontinua can coherently add up yielding subcycle fieldwaveforms, some basic concepts and models of ultrafast nonlinear optics have to be revisited. Originally intendedto refer to a rapid buildup of the spectral bandwidth of ultrashort laser pulses propagating, as waveguide modes oras free beams, in media with a third-order optical nonlinearity, within the past decade, the term“supercontinuumgeneration”has been seamlessly extended, thanks to its all-embracing character, to include very-high-order andnonperturbative nonlinear optical processes and now applies to ultrabroadband field waveform generation in theultraviolet and x-ray ranges, as well as high-harmonic attosecond and zeptosecond supercontinua. This paperoffers a brief overview of this rapidly growing field of research.
