驻波场中原子的跃迁速率与所受辐射压力的关系

THE RELATION BETWEEN THE RADIATION FORCE ON AN ATOM IN THE STANDING WAVE FIELD AND THE ATOMIC TRANSITION RATE

从二能级原子的密度矩阵运动方程出发,研究了原子在驻波场中的受激吸收速率、受激辐射速率和辐射压力的对应关系,提出了在驻波场中原子所受的辐射压力由受激吸收力和受激辐射力构成。此观点可以推广至N个行波场和原子相互作用的情况。

Based on equation of motion of the two-level atomic density matrix, we have studied theoretically the relation between the radiation force on an atom in the standing wave field and the atomic induced absorption rate and induced radiation rate. We find that the radiation force on an atom in the standing wave field consists of induced absorption force and induced radiation force. This piont of view is also valid in the circumstance of interaction between an atom and N plane waves.
