【摘要】 研究了射频驱动精细结构能级跃迁引起的电磁诱导透明(EIT)和电磁诱导吸收(EIA)的转化.通过采用射频场同时驱动激发态和基态精细结构能级跃迁,使系统中出现EIT和EIA.研究结果表明,调谐射频场频率从与基态精细结构能级共振到与激发态精细结构能级共振的过程中,EIT和EIA相互转化,而且射频场的拉比频率取值不同,EIT和EIA的变化规律也不同.更多还原

【Abstract】 Transformation of electromagnetically induced transparency(EIT) and electromagnetically induced absorption(EIA) due to radio-frequency field driving hyperfine levels is discussed.EIT and EIA are observed when the radio-frequency field interacts with hyperfine levels within both excited state and ground state.It can be shown that the frequency and feature of EIT and EIA change when the radio-frequency field is tuned from resonant with hyperfine levels of ground state to resonant with hyperfine levels of excited state.Furthermore,the change is related to the Rabi frequency of radio-frequency field.更多还原
