    "abstract": "We propose a new laser cooling method for atomic species whose level\nstructure makes traditional laser cooling difficult. For instance, laser\ncooling of hydrogen requires single-frequency vacuum-ultraviolet light, while\nmultielectron atoms need single-frequency light at many widely separated\nfrequencies. These restrictions can be eased by laser cooling on two-photon\ntransitions with ultrafast pulse trains. Laser cooling of hydrogen,\nantihydrogen, and many other species appears feasible, and extension of the\ntechnique to molecules may be possible.",
