Abstract
This thesis describes the construction of a new laboratory and a new apparatusfor ultracold strontium experiments. It also describes the the creation of the first
strontium grating magneto-optical trap (MOT). The new strontium apparatus has
been improved to provide high, and controllable atomic flux, high magnetic field
coils, low vacuum pressure, plenty of optical access, and a streamlined computer
control system. This flexible apparatus is designed to operate several potential
experiments.
Our work with strontium grating MOTs will help to enable the creation of
compact, stable, and portable quantum devices that harness the unique capabilities
of alkaline earth atoms. We present the construction of the grating MOT apparatus,
the demonstration of the broad line strontium grating MOT, and the transfer to the
narrow line grating MOT. In addition, we show the effectiveness of sawtooth wave
adiabatic passage (SWAP) in the grating MOT geometry.
Lastly, we present work from the previous apparatus, measuring the isotope
shifts on the clock and intercombination transitions in strontium.
