Atomic coherence effects in the ion-trap laser

This work focuses on fundamental theoretical and experimental aspects of relativistic beam physics, recoil, and cooling phenomena in atomic and ion beams and traps, emphasizing coherence and collective effects. The physics of atomic laser and free electron laser, and the development of a bridge between them through the mechanism of the so-called recoil induced gain mechanism, is also examined, as are the links between relativistic beam physics and atomic laser physics. Topics include: laser cooling of trapped ions; optical lattices; spatio-temporal instabilities in optical systems; coherence in atom optics; coherent population trapping; two-level gain and collective recoil-induced effects; high-gain free electron laser - theory, experiments and projects; cooling of ion beams in a storage ring; and experiments on dense laser-cooled stored ion beams.

Trapped ions are one of the most promising candidates for quantum information applications. We describe an experimental setup using a linear rf Paul trap for confining 171Yb+ ions. In particular, the required lasers and lock setups are described. One of the key requirements for qubit manipulation is achieving high fidelity state-selective detection. A well established means to accomplish this is through the use of laser fluorescence. The fluorescence theory of 171Yb+, including the effect of coherent population trapping which can suppress the fluorescence, is documented together with the counter-acting effect of a magnetic field. In addition, the fluorescence theory of 174Yb+, which has simpler atomic structure, is also described for comparison. The resonance fluorescence behaviour of both isotopes is studied experimentally as a function of magnetic field, laser polarization, power and detuning. The experimental results for both isotopes agree with theoretical models, including the effect of coherent population trapping.
