Abstract
A statistical-mechanics theory of nonlinear many mode laser systems was presented. It was stated that pulse formation is a first-order phase transition of spontaneous ordering of modes in an effective thermodynamic system. It was shown that thermodynamics depends on a single parameter. It was also shown that the thermodynamics is independent of the gain saturation mechanism and that it is correctly reproduced by a mean field calculation.
