    "abstract": "Double dark resonances originate from a coherent perturbation of a system\ndisplaying electromagnetically induced transparency. We experimentally show and\ntheoretically confirm that this leads to the possibility of extremely sharp\nresonances prevailing even in the presence of considerable Doppler broadening.\nA gas of 87Rb atoms is subjected to a strong drive laser and a weak probe laser\nand a radio frequency field, where the magnetic coupling between the Zeeman\nlevels leads to nonlinear generation of a comb of sidebands.",
