Unified Thermodynamics of Dissipative Structures and Coherence in Nonlinear Optics
Threshold phenomena in lasers and nonlinear optics have been studied extensively by theoreticians within the last decade, mainly by means of microscopic, quantum mechanical approaches[1,2]. However, in recent times, the macroscopic nature of many of the important results like probability densities and linewidths was made apparent by showing their pronounced analogy to results of the macroscopic Landau theory of phase transitions. Therefore, it became interesting to look at these threshold phenomena also from a macroscopic point of view.
