# Spontaneous localization in self-focusing of ultrashort light pulses

## TL;DR

This paper investigates the spontaneous formation of self-localized light wave packets, known as light bullets, in ultrashort pulse self-focusing experiments, exploring their production and fundamental nature in nonlinear media.

## Contribution

It provides new insights into the spontaneous localization phenomena of light bullets in ultrashort pulse self-focusing, advancing understanding of their formation and properties.

## Key findings

- Light bullets can form spontaneously during self-focusing of ultrashort pulses.
- The nature of these localized wave packets is characterized in detail.
- Insights into the conditions for stable light bullet formation.

## Abstract

This is a summary directed to PhD students of the research work conducted on the problem of the production of "light bullets", or multidimensional wave packets that propagate without distortion in unbounded, homogeneous, nonlinear media, and on the actual nature of the self-localized light wave packets spontaneously generated in self-focusing experiments with ultrashort pulses.
