From: Carrier thermometry of cold ytterbium atoms in an optical lattice clock
The clock transitions of different motional states in optical lattices. (a) Five dominant spectral features: the central carrier (black arrow) where the motional state is conserved; the first-order and second-order red sidebands (red arrows) where the motional state decreases; the first-order and second-order blue sidebands (blue arrows) where the motional state increases. (b) The spectrum including carrier, first-order sidebands and second-order sidebands.
