A 674 nm external cavity diode laser for a ⁸⁸Sr⁺ ion trap
… processing. In this thesis, a 674 nm extended cavity diode laser is built to address an optical quantum bit in ⁸⁸Sr⁺ with the goal of testing such traps. To find this transition, a depletion experiment is performed in which the 674 nm transition depopulates the principal 422 nm transition, …

A narrow linewidth diode laser system for strontium laser cooling applications
The diode laser system for laser cooling on the 1S 0 → 3P1 intercombination line of strontium discussed in this thesis allows us to cool and trap an atomic strontium sample to 15 muK. Samples in this temperature range are useful for the development of the next generation of atomic frequency …

Progress Towards a Spinor Bose-Einstein Condensate Machine
Laser cooling and trapping of neutral particles has become a major area of research in atomic physics with the discovery of the first Bose-Einstein condensates (BECs) in 1995. These ultracold atomic vapors allow for study of fundamental quantum electromagnetic properties of atoms that are otherwise …

Towards single Ce ion detection in a bulk crystal for the development of a single-ion qubit readout scheme
… line of Ce ions were measured using an external cavity diode laser (at 371 nm) as the excitation source. The difference in the permanent dipole moment of the ground and excited states of Ce ions was measured in a photon echo experiment on Pr ions in a Ce-Pr co-doped Y2SiO5 crystal. The …
