Abstract

We show that a laser with conventional optical feedback is symmetric under any rotation of the electric field, whereas a laser with phase-conjugate feedback is symmetric only under the rotations of the electric field over 0 and $\pi$. This has important consequences for dynamics and bifurcations. Most importantly, a PCF laser shows symmetry breaking and restoring bifurcations, something that does not occur in a COF laser.
