考虑自发辐射后原子在激光衰波场中的传输

The Transmission of Atoms in an Evanescent Laser Wave by Considering the Spontaneous Emission

本文考虑了自发辐射对原子波函数的影响，得到了激光衰波作用下含自发辐射的原子波函数传输解。在此基础上我们数值计算了基态和激发态原子的波场结构，发现在负失谐情形，当Ｒａ－ｂｉ频率较大和光子反冲能大于一阶失谐能时，原子会被束缚在靶面附近。

Considering the sqontaneous emission, we have obtained a transmission solution of the atomic wave function in an evanescent laser wave, We calculated numerically the wave structure of the excited and ground state atom. Our numerical results show that it is possible to hold the atoms near the target when Rabi frequency is large and the photon recoil energy is greater than the detuning energy in the case of negative detuning. We also have interpreted the phenomenon by using of the radiation force and radiation potential energy.
