Effects of Quantum Interference on the Profile of Excitation Spectra in the Atomic Sodium D1
Effects of Quantum Interference on the Profile of Excitation Spectra in the Atomic Sodium D1
摘要
Abstract
In this paper, an experiment in a sodium vapor cell with cw laser pumping is reported. Two dips in the excitation spectrum profile of the sodium D1 line are observed. Theoretically excitation spectra in the three-level system are calculated in detail and results are identical with experiments. It is demonstrated that the appearance of the two dips in the excitation spectrum is close connected with quantum interference effect.
