Abstract
We analyze the Fresnel number and gain dependence of the spatiotempora l dynamics of a dye laser. The results support the existence of ordere d behavior in the low-Fresnel-number and low-gain regions and a transi tion to spatiotemporal. disorder when the Fresnel number and/or the ga in are increased. The disordered state has a surprisingly small correl ation length (much smaller than the system size), supporting the idea that turbulence is possible in laser systems.
