| 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>+|32P3/2>Na和Ar的碰撞截面。关键词：

| 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〉+│32P3/2>〉 Na and Ar. |
