A laser consisting of two independently pumped resonators can exhibit mode bifurcations that evolve out of the exceptional points (EPs) of the linear system at threshold. The EPs are non-Hermitian degeneracies occurring at the parity–time-reversal (PT) symmetry-breaking points of the threshold syste...
