    "abstract": "We show that Coherent Population Oscillations effect allows to burn a narrow\nspectral hole (26Hz) within the homogeneous absorption line of the optical\ntransition of an Erbium ion-doped crystal. The large dispersion of the index of\nrefraction associated with this hole permits to achieve a group velocity as low\nas 2.7m/s with a ransmission of 40%. We especially benefit from the\ninhomogeneous absorption broadening of the ions to tune both the transmission\ncoefficient, from 40% to 90%, and the light group velocity from 2.7m/s to\n100m/s.",
