Abstract

Double phase conjugate mirror (DPCM) is a unique device in which two mutually incoherent pump beams are phase conjugated¹ simultaneously, (Fig. 1, inset). Currently there is a disagreement in the field about the nature of the linear instability (oscillator or amplifier^1,2). The controversy originates from the wide gap in complexity between the analytical problems considered and the usual experimental conditions. The more realistic, numerical studies³ and experiments exhibit a rich spatial behavior for the DPCM. The nature of the linear instability is essential for understanding the behavior of DPCM in different regimes and hence for improving the device performance.
