Abstract

We introduce a new, quantitative experimental signature–formation of a characteristic chain-link pattern in laser irradiance profiles–of thermal-blooming phase-compensation instability with uniform wind. We exhibit such chain links observed in computer simulation and in the laboratory, and we derive the main features of the observed chain link from first principles. This derivation represents what is to our knowledge the first practical application of linearized instability analysis to real systems with spontaneously generated unseeded phase-compensation instability.
