Stimulated emission and phase transitions

Attention is drawn to a close analogy between lasers and stimulated generation of a Bose condensate of Cooper pairs in a superconductor. The same analogy should apply also to the processes associated with phase transitions in the expanding universe. On the basis of this analogy we can postulate a complex dynamics of the processes that have occurred during the earlier stages of the evolution of the universe. In particular, we can expect regimes which are described by a strange attractor.
