# Self-organized compound pattern and pulsation of dissipative solitons in a passively mode-locked fiber laser

## TL;DR

This paper reports the experimental observation of self-organized soliton patterns and pulsations in a passively mode-locked fiber laser, highlighting the role of optomechanical interactions and spectral dynamics.

## Contribution

It demonstrates the formation of equidistant soliton bunches and their pulsation behavior, revealing new insights into soliton self-organization in fiber lasers.

## Key findings

- Soliton bunches form with equidistant spacing.
- Solitons exhibit pulsation with periods tied to cavity round trips.
- Kelly sidebands appear periodically, synchronized with pulsation.

## Abstract

We experimentally observe soliton self-organization and pulsation in a passively mode-locked fiber laser. The optomechanical interaction in the optical fiber is key to the formation of equidistant soliton bunches. These solitons simultaneously undergo a pulsation process with a period corresponding to tens of the cavity round trip time. Using the dispersive Fourier transformation technique, we find that the Kelly sidebands in the shot-to-shot spectra appear periodically, synchronizing with the pulsation.
