The optical properties of a caesium atomic beam driven on a resonant hyperfine transition in the D(2) line were studied as a function of the probe laser frequency. Using a third off-resonant laser system, a heterodyne interferometer allowed simultaneous absorption and phase shift measurements of either the probe or the coupling laser. The signal features of the probe and coupling laser transmitted intensities showed strong differences in the vicinity of the hyperfine transitions excited by the probe laser. Regular absorption signals and electromagnetically induced transparency were found in either transmitted intensities. Furthermore, light induced birefringence of the probe laser was measured.
研究了在D(2)线的共振超精细跃迁上驱动的铯原子束的光学性质与探测激光频率的函数关系。使用第三个非共振激光系统，外差干涉仪允许对探测激光或耦合激光进行同时吸收和相移测量。探测激光和耦合激光透射强度的信号特征在探测激光激发的超精细跃迁附近表现出很大差异。在两种透射强度中都发现了规则的吸收信号和电磁诱导透明。此外，还测量了探测激光的光致双折射。
