    "abstract": "We have studied a general technique for laser cooling a cloud of polarized\ntrapped atoms down to the Doppler temperature. A one-dimensional optical\nmolasses using polarized light cools the axial motional degree of freedom of\nthe atoms in the trap. Cooling of the radial degrees of freedom can be modelled\nby reabsorption of scattered photons in the optically dense cloud. We present\nexperimental results for a cloud of chromium atoms in a magnetic trap. A simple\nmodel based on rate equations shows quantitative agreement with the\nexperimental results. This scheme allows us to readily prepare a dense cloud of\natoms in a magnetic trap with ideal starting conditions for evaporative\ncooling.",
