在铷原子D1线（794.8 nm）的三能级Λ型系统的一个臂上观察到电磁感应透明，当另一臂上有抽运场时，吸收减少85%，这种对弱探测场的吸收减少是由于强抽运场产生的原子相干性。该实验是在室温下的铷蒸气室中进行的，使用连续波二极管激光器以无多普勒配置提供泵浦光束和探测光束。一个简单的理论处理，包括多普勒展宽是在良好的定性与实验测量。
An electromagnetically induced transparency is observed at one arm of a three-level Λ-type system in a rubidium D1 line (794.8 nm) with an 85% reduction in absorption, when a pumping field is present at the other arm. This reduction in absorption for the weak probe field is due to the atomic coherence produced by the strong pumping field. This experiment is done in a Rb vapor cell at room temperature with cw diode lasers for both pumping and probe beams in a Doppler-free configuration. A simple theoretical treatment including Doppler broadening is in good qualitative agreement with the experimental measurement.
