Scar modes are in particular the sub ject of our investigations. We study their imprints on the statistics of intensity and we show how the introduction of a localized gain region in the fiber is used to perform a selective excitation of scar modes.13 pagesOpticsOther Condensed MatterStatistical MechanicsChaotic Dynamicstext
