    "abstract": "We consider pump-probe spectroscopy of a single ion with a highly metastable\n(probe) clock transition which is monitored by using the quantum jump\ntechnique. For a weak clock laser we obtain the well known Autler-Townes\nsplitting. For stronger powers of the clock laser we demonstrate the transition\nto a new regime. The two regimes are distinguished by the transition of two\ncomplex eigenvalues to purely imaginary ones which can be very different in\nmagnitude. The transition is controlled by the power of the clock laser. For\npump on resonance we present simple analytical expressions for various\nlinewidths and line positions.",
