Abstract
We study experimentally the influence of the molecular dynamics in the loca l intensity fluctuations of large aperture dye lasers, and find dependencie s on solvent viscosity and active molecular size. This is an example of the complexity of the still quite unknown nonlinear processes that underlie th e pattern formation dynamics in large aperture optical systems, in which th e diffraction has lost influence and the bulk dynamics dominate.
