摘　　要：研究了V型三能级原子的玻色-爱因斯坦凝聚体(BEC)与双模压缩相干态光场相互作用系统的量子动力学行为,分析了利用V型三能级原子BEC与双模压缩相干态光场相互作用制备双模原子激光的可能性。结果表明:在光场作用下,V型三能级原子BEC中被激发到非俘获态的原子,仍保持其相干态的特性,从而在理论上证明了利用V型三能级原子BEC与双模压缩相干态光场相互作用可以产生双模原子激光.We have studied the quantum dynamic behavior of system of two-mode squeezed field interacting with Bose-Einstein condensate of V-type three-level atoms, and analyzed the possibility of preparation of two-mode atomic laser via interaction of two-mode field and Bose-Einstein condensate of V-type three-level atoms. It is shown that the atoms from trapped state in Bose-Einstein condensate excited to untrapped states by two-mode radiation frequency maintain properties of coherent states. This result predicts theoretically that two-mode atomic laser can be prepared via interaction of two-mode field and Bose-Einstein condensate of V-type three-level atoms.
