在本論文中，我們在冷原子系統中研究了由電磁誘發透明引起的慢光效應。我們對三種不同電磁誘發透明系統（Λ型、V型和級聯型配置）中光脈衝的減速進行了比較，實驗觀察結果與理論預測相符。我們的研究結果促進了我們對不同電磁誘發透明配置下慢光現象的理解。

In this thesis, we investigate the slow-light effect induced by electromagnetically induced transparency (EIT) in a cold atomic system. We compare the deceleration of light pulses among three distinct transparent systems (Λ-type, V-type, and cascade-type EIT configurations), the experimental observations are consistent with theoretical pre dictions. Our research findings contribute to our understanding of slow-light phenomena in different EIT configurations.
