  We present results of cellular automata based investigations of rotating
spiral autowaves in a nonequilibrium excitable medium which models three-level
paramagnetic microwave phonon laser (phaser). The computational model is
described in arXiv:cond-mat/0410460v2 and arXiv:cond-mat/0602345v1 . We have
observed several new scenarios of self-organization, competition and dynamical
stabilization of rotating spiral autowaves under conditions of cross-relaxation
between three-level active centers. In particular, phenomena of inversion of
topological charge, as well as processes of regeneration and replication of
rotating spiral autowaves in various excitable media were revealed and
visualized for mesoscopic-scale areas of phaser-type active systems, which
model real phaser devices.
