Nonlinear dynamical phenomena in a four-frequency ring gas class-a laser with elliptically polarized elgenstates

摘要

Spontaneous pulsations of intensities, continuous change of instantaneous phase difference between counterrunning waves on π at transition from negative to positive tunings while their mean phase difference remains unaltered as well as jumps on 2π of mean phase differences were found in a four-frequency ring gas class-A laser with elliptically polarized eigenstates in the presence of linear coupling.
