Twisted speckle entities inside wavefront reversal mirrors

Abstract

The previously unknown property of the optical speckle pattern reported. The interference of a speckle with an oppositely moving phase-conjugated speckle wave produces a randomly distributed ensemble of a twisted entities (ropes) surrounding optical vortex lines. These entities appear in a wide range of randomly chosen speckle parameters inside the phase-conjugating mirrors regardless to an internal physical mechanism of the wavefront reversal. These numerically generated interference patterns are relevant to a Brillouin $\mathbf{PC}$-mirrors and to a four-wave mixing $\mathbf{PC}$-mirrors based upon laser trapped ultracold atomic cloud.
