Instabilities and Structure Formation

Abstract

Instabilities are observed in many different types of laser processing. They are related to positive feedbacks between different characteristics (degrees of freedom) in laser—matter interactions. The appearance of an instability means that a small perturbation of the system initially grows exponentially with time. Its further development can lead to different self-organization phenomena, such as spontaneous formation of periodic or stochastic dissipative structures, spiral waves, and many other structures with broken or unbroken symmetry (‘unbroken’ refers to transformations from an unstable structure to a stable or metastable structure without changes in initial symmetry).
