Intensity clamping of a femtosecond laser pulse in condensed matter
TLDR
In this paper, the supercontinuum spectrum of an intense femtosecond Ti:sapphire laser pulse propagating in condensed optical media (water, chloroform and glass), at various input laser energies, below and above the threshold for filamentation of the laser pulse was measured.About:

The propagation of powerful femtosecond laser pulses in opticalmedia: physics, applications, and new challenges
See Leang Chin,S.A. Hosseini,Weiwei Liu,Q. Luo,Francis Théberge,Neset Akozbek,Andreas Becker,V. P. Kandidov,Olga G. Kosareva,Hartmut Schroeder +9 more
TL;DR: In this paper, a femtosecond laser pulse propagates in an optical medium, self-focusing occurs, and the most powerful part of the pulse self focuses first during its propagation.
Journal ArticleDOI
Plasma density inside a femtosecond laser filament in air: strong dependence on external focusing.
TL;DR: The experiment shows that external focusing strongly influences the plasma density and the diameter of femtosecond Ti-sapphire laser filaments generated in air and is in good qualitative agreement with the results of numerical simulations.

Filamentation of high-power femtosecond laser radiation
TL;DR: The state of the art of investigations on filamentation of a high-power femtosecond laser radiation in transparent media is reviewed in this article, where the physical picture of this phenomenon is presented and its relation to the fundamental concepts of nonlinear optics and practical applications is demonstrated.

Self-transformation of a powerful femtosecond laser pulse into a white-light laser pulse in bulk optical media (or supercontinuum generation)
V.P. Kandidov,Olga G. Kosareva,I.S. Golubtsov,Weiwei Liu,Andreas Becker,Neset Akozbek,Charles M. Bowden,See Leang Chin +7 more
TL;DR: In this article, it was shown that the high spatio-temporal localization of the light field in the filament, which enables the supercontinuum generation, is sustained due to the dynamic transformation of light field on the whole transverse scale of the beam, including its edges.

Observation of Self-Phase Modulation and Small-Scale Filaments in Crystals and Glasses
Robert R. Alfano,S. L. Shapiro +1 more
TL;DR: In this paper, small-scale filaments were observed in calcite, quartz, sodium chloride, and several glasses under picosecond pulse excitation, and the physical mechanism responsible for these processes is the change in refractive index resulting from electronic distortion.
