    "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 vacuum-ultraviolet laser light, while\nmultielectron atoms need laser light at many widely separated frequencies.\nThese restrictions can be eased by laser cooling on two-photon transitions with\nultrafast pulse trains. Laser cooling of hydrogen, antihydrogen, and carbon\nappears feasible, and extension of the technique to molecules may be possible.",
