Abstract
In recent years, much attention was paid to investigating the chaotic generation of lasers. For example, scenarios and characteristics of chaotic generation in an unstable cavity of a fast-flow laser with spatially inhomogeneous pumping were studied in [1]. A scheme of optical information chaos on the basis of lasers that synchronously operate in a chaotic regime with chaotic pumping was considered in [2]. Both scaling and fractal dimension are important characteristics of nonlinear systems with dynamic chaos [3]. The existence of scaling properties for harmonic radiation in laser plasmas under the action of high-power pumping was indicated in [4]. The mode structure for the radiation of an unstable-cavity laser was demonstrated to be fractal [5]. The fractal dimensions of the radiation-intensity distribution for lasers with narrow slit-shaped and circular apertures were found to be D = 1.6 and 1.3, respectively.
