    "abstract": "It is discussed the limitations of the widely used markovian approximation\napplied to model the turbulent refractive index in lightwave propagation.\n  It is well-known the index is a passive scalar field. Thus, the actual\nknowledge about these quantities is used to propose an alternative stochastic\nprocess to the markovian approximation: the fractional Brownian motion. This\ngeneralizes the former introducing memory; that is, there is correlation along\nthe propagation path.",
