TL;DR: Nonlinear optical media that are normally dispersive support a new type of localized wave packets that are X shaped in space and time and have slower than exponential decay, thus playing an important role in experiments.

TL;DR: The authors' measurements show that the self-trapped wave is an X-shaped light bullet spontaneously generated from a standard laser wave packet via the nonlinear material response (i.e., second-harmonic generation), which extend the soliton concept to a new realm, where the main hump coexists with conical tails which reflect the symmetry of linear dispersion relationship.

TL;DR: In this article, the authors discuss the main issues of optical parametric chirped pulse amplification and overview recent progress in the field and discuss a broad class of femtosecond laser systems with output power ranging from a few gigawatts to hundreds of terawatts, with the potential of generating few-optical-cycle pulses at the petawatt power level.

TL;DR: In this article, a femtosecond traveling-wave parametric generator with a parametric superfluorescence seed source and parametric amplifier was proposed. But the performance of the generator was limited to 1-ps and 200-fs pulses at wavelengths of 0.53 and 0.6 μm, respectively.

TL;DR: In this article, the concept of optical parametric chirped-pulse amplification is applied to attain pulses with energies up to 8 mJ and a bandwidth of more than 100 THz.
