摘要
将简并双光子微脉塞的量子理论推广到非简并情形,给出了原子发射几率的解析表达式并且分析了相应的性质.发现由于在微脉塞中存在两种腔场模式,导致有两个自由度来改变原子在经过腔场时所受到的势场,因此非简并双光子微脉塞的发射几率的行为不同于简并双光子情况下的发射几率.
The quantum theory of the two-photon mazer, previously limited to the degenerate case, is extended to the non-degenerate situation. The analytical expression for the atomic emission probability is obtained and the corresponding behavior is investigated. The results show that the emission probability behaviors in the non-degenerate two-photon mazer differ from those in the degenerate two-photon mazer,since two cavity modes are allowed in the mazer so that there are two freedoms changing the potentials that the atoms experience as they transit the cavity.
