We have demonstrated that interruptions of macroscopic duration appear in the 493-nm fluorescence of a single trapped and cooled Ba+ ion. They are caused by sudden transitions of the ion into the “dark” 2D5/2 state. — Multiple simultaneous jumps of three ions indicate cooperative interaction with the light.
