Abstract: Summarizing the work comprising the thesis, we explored interactions of ultracold dilute gas of atoms with ions and with a cavity. The interaction of lighter ions with the localized ensemble of ultracold atoms lead to the observation of cooling of the ions. The interactions of the same atoms with the cavity was then explored. In particular, the use of tunable optical bistability was explored for switching of light using light. Driven atoms placed inside the cavity resulted in the emission of light from the cavity, this light showed features of lasing when the cavity was tuned to the red of the optical transition. Preliminary experiments towards creating molecules inside a cavity were performed and how to distinguish molecular signal from the atomic signal is discussed. Use of a cavity to detect diatomic molecules was also explored. Finally, we conclude the thesis with future directions, which involve observing interactions between ultracold molecules.
