Excitation probability to the 
state of the probe ion as a function of the detuning. Red: excitation time of 900 μs, together with a relatively low intensity resolves individual normal modes. Visible are the normal modes of the x direction. Blue: a short high-intensity pulse of length 8 μs excites superpositions of the normal modes. Green: fit of the excitation to a sinc-function with only the amplitude and centre frequency as free parameters.
