Surface trap for ytterbium ions
… planar ion trap from a cold atom source of Ytterbium using photoionization. The surface trap consisted of a three-rod radio frequency Paul trap fabricated using standard printed circuit board techniques. The cold atom source was an isotope-selective magneto-optical trap of …

High-power diode-pumped ytterbium-doped fibre-laser
… details the work I have done on double cladding ytterbium-doped fibre lasers. The two main subjects developed were the study of an efficient compact-launching system, and the operation of the double cladding compact fibre as a continuous-wave laser and a Q-switched laser. During this work, highly …

Cavity quantum electrodynamics with ensembles of ytterbium-171
… side. With this structure, we are able to probe ytterbium-171 atoms in both the weak and strong coupling regimes of cavity quantum electrodynamics. This asymmetric micromirror structure simultaneously offers strong light-atom coupling, mechanical robustness, and excellent access to a large cavity …

Precision Metrology with Ytterbium Ions for New Physics Search
… using isotope shifts of optical transitions in Ytterbium. We conduct the isotope shift experiment by measuring ions one at a time and in a co-trapped configuration following the protocol of correlation spectroscopy. We study the systematic uncertainty budget for both types of measurements. We …

High power pulsed ytterbium doped fibre lasers and their applications
The aim of my project is to develop pulsed Ytterbium (Yb) doped fibre master oscillator power amplifier (MOPA) systems seeded by semiconductor lasers. I was principally focused on two specific projects aligned to sponsored programs of research within the ORC pulsed fibre laser group: the first …

Electron spin-lattice relaxation in ytterbium ion-doped silicate glass
"Relaxation rates of Yb$\sp{3+}$ ions incorporated in low concentrations into a host silicate glass have been measured using a pulse saturation/recovery technique at 9.5 GHz over the temperature range 1.5-7.0 K. Compared with similar measurements made on crystalline material, the temperature …

A Cavity-stabilized diode laser for dipole trapping of ytterbium
… laser due to its 44 mHz linewidth. For ytterbium to be used efficiently as a gain medium, its inhomogeneous broadening must be suppressed to a level lower than the linewidth of its gain transition. In this thesis, I design, implement, and characterize an optical lattice trap for …

High-power cladding-pumped Raman and erbium-ytterbium doped fibre sources
… lasers have been based on highly efficient ytterbium-doped fibre, while progress to power-scale other rare-earth doped fibres and fibre Raman laser has been much more modest.<br/><br/>This thesis can be divided into two main themes. The first concerns the power-scaling and study of …

Erbium-ytterbium-yttrium compounds for light emission at 1.54[mu]m
… device design challenges. In this thesis, erbium-ytterbium oxide (Er.Yb2.0 3) and erbium-ytterbium-yttrium silicate (ErxYbYY 2 ,ySi 2O7 ) compounds are investigated as novel materials systems for the development of EDWAs. The high erbium and ytterbium solubility (>1022 cm-3) and refractive index …
