本文主要研究室溫下熱銣原子中電磁波誘發透明(Electromagnetically Induced Transparency)的量子干涉現象，熱原子因為處在相較冷原子高的溫度中，所以環境能影響EIT的因素較多，像是都卜勒效應、原子之間的碰撞等等。
實驗中使用Λ-type EIT，在不外加幫浦光的狀況下，透過調整不同的變因，像是溫度、雷射光大小和外加紫外光來觀察EIT，試著釐清不同的變因對於室溫下熱銣原子的EIT效率以及圖形的影響。

The experiment in this thesis is related to the phenomenon called Electromagnetically Induced Transparency(EIT) in rubidium 85 at room temperature. In thermal atoms, there are many factors from circumstances to influence the EIT system, like Doppler effect, collisions between atoms, etc. We use a Λ-type EIT system in our experiment. Under the condition without optical pumping, we adjust different factors, like temperature, the beam size of lasers and irradiating UV light, to figure out how they affect on the efficiency and the spectrum shapes of EIT.
