Abstract

This thesis presents my work on exploring Light Induced Atomic Desorption (LIAD) for ultracold atom experiments. With LIAD, it is possible to achieve faster control over the atomic vapor larger number of trapped atoms, which improves the signal strength in experimental measurements. The basic physical principles governing the MOT are explained and a simple mathematical model is presented to clarify the MOT fill dynamics. An overview of the LIAD effect and its mechanism are presented and the observation of LIAD effect demonstrated a factor of 5.5 ubcrease in the number of atoms and decreased the time constant of the MOT fill by factor of 2.
