摘　　要：提出一种制备双模场对相干态的方法.在本方法中,两个级联型三能级原子逐个地穿过两个初始时处于真空态的单模腔,然后对原子进行探测,在一定条件下,两个腔模被制备到对相干态.A scheme is proposed for generation of pair coherent states of two modes field.In the scheme two ladder-type three-level atoms are sent through two initially empty single-mode cavities and then are detected.under certain conditions,the two cavity modes are prepared in pair coherent states.

关 键 词：对相干态 双模场 级联型三能级原子
