Injection Locking of a Trapped Ion Phonon Laser — •Valentin Batteiger1, Sebastian Knünz1, Maximilian Herrmann1, Guido Saathoff1, Theodor W. Hänsch1, Thomas Udem1, and Kerry Vahala2 — 1Max-Planck-Institut für Quantenoptik, Garching, Germany — 2California Institute of Technology, Pasadena, CA, USA
A single trapped ion is addressed by two laser beams, one tuned below, one above an atomic resonance. This opto-mechanical system can perform stable self-sustained oscillations, which we describe in close analogy to optical lasers [1]. We show the basic operation principle and present injection locking of the ion's motion to an externally controlled signal. Reference: [1] K. Vahala et al., Nature Physics 5, 682 (2009).
