abstract = {The dynamics of patterns emerging from a photorefractive two-wave
mixing geometry, where tilted single
feedback mirror gives rise to an advection-like effect, is
studied experimentally. The nonlocal coupling
(introduced by the tilting angle) between the two
counterpropagating beams, the strength of the nonlocal
response of the photorefractive medium, cause the existence of:
(i) the seeding of new pattern geometry, (ii)
an inversion of pattern transverse phase velocity, (iii) a
bifurcation from convective to absolute instabilities.}
