    "abstract": "The order of high harmonics emitted by an atom in an intense laser field is\nlimited by the so-called cutoff frequency. Solving the time-dependent\nSchr\\\"odinger equation, we show that this frequency can be increased\nconsiderably by a parabolic confining potential, if the confinement parameters\nare suitably chosen.\n  Furthermore, due to confinement, the radiation intensity remains high\nthroughout the extended emission range. All features observed can be explained\nwith classical arguments.",
