EIT also has significant applications in fundamental physics and nonlinear optics. Given that EIT is a foundational component of future quantum technology, a comprehensive understanding of its parameters is essential for the development of future devices. This thesis focuses on the transient dynamics of EIT, specifically examining oscillations in the absorption of the Probe Field (PF) as a means to determine the decoherence of the ground states. Transient EIT has been explored in previous theoretical and experimental studies across various systems, including Cold Atoms (CAs) and hot vapor media. Here, transient EIT is studied theoretically, numerically, and experimentally. Parameter exploration has been conducted to understand the effects of different parameters on the transient behavior of EIT and to identify which decoherence mechanisms have the most significant impact on the quality of EIT. Experimentally, we explored a hot atomic vapour of, naturally abundant Rubidium (Rb) atoms. Additionally, progress towards constructing a CAs system, using a Magneto-Optical Trap (MOT) from scratch was made, opening the door to future studies of this system.enAvailable to the World Wide WebEITQuantum memoryElectromagnetically induced transparencyQuTiPMOTMagneto-optical trapThesis
