    "abstract": "We propose a simple and effective way of creating pure dark superposition\nstates. The generation of pure states is carried out by using bichromatic\nradiation with controllable polarization ellipticity. We derived analytic\nformulas for polarization elipticity to obtain pure dark states of different\nZeeman sublevels of alkali atoms. Experimentally we accumulated ~60% of the\natoms in the 0-0 dark state of the D1 line of Rb87",
