Abstract
We show that the onset of laser multiple filamentation can be described as a critical phenomenon that we characterize both experimentally and numerically by measuring a set of seven critical exponents. This phase transition deviates from any existing universality class and offers a unique perspective of conducting two-dimensional experiments of statistical physics at a human scale.

Laser Filaments Go through Phase Transition
Published 13 February 2015
A powerful laser beam separates into many smaller filaments that undergo a phase transition similar to fluid percolating through a porous material.
