    "abstract": "The paper presents a critical analysis of publications devoted to one of the\nmethods for production of the so-called \"slow light\" (the light with an\nanomalously low group velocity) due to extremely high local steepness of the\ndispersion curve of the medium. The method in point employs for this purpose\nthe effect of coherent population oscillations accompanied by burning of a\nnarrow spectral hole in the homogeneously broadened absorption spectrum.\nPhysical model of the effect proposed in the studies under consideration is\nbased on analysis of response of a nonlinear medium to a low-frequency\nintensity modulation of the incident light beam. We show that all the\nobservations described in these papers can be easily interpreted in the\nframework of the simplest model of saturable absorber and have nothing to do\nwith the effects of hole burning and group velocity reduction.",
