【摘要】 分析了三能级原子系统对激光脉冲的响应。由此导出了双光子三能级光子回波形成条件。在实验上观察到这种新的光子回波,并用其测量了|3²D>+|3²P_3/2>Na和Ar的碰撞截面。更多还原

【Abstract】 The response of an atomic tri-level system to laser pulses was analyzed and the condition for forming tri-level echo was obtained. This new echo has been observed experimentally and used to measure the collisional cross-section between │3²D〉+│3²P_3/2〉 Na and Ar.更多还原
