In order to fully exploit laser beam dynamics in multimode fibers for applications to spatiotemporal laser beam mode-locking, it is necessary to accurately determine the conditions for the occurrence of the effect, by optimizing the spatial and temporal properties of the input laser pulses. We will describe a series of recent experiments that permit to unveil the physical mechanism of Kerr-beam self-cleaning, based on a complex cascade of parametric wave mixing processes.

Abstract
In order to fully exploit laser beam dynamics in multimode fibers for applications to spatiotemporal laser beam mode-locking, it is necessary to accurately determine the conditions for the occurrence of the effect, by optimizing the spatial and temporal properties of the input laser pulses. We will describe a series of recent experiments that permit to unveil the physical mechanism of Kerr-beam self-cleaning, based on a complex cascade of parametric wave mixing processes.| File | Dimensione | Formato | |
