我们证明了一个光偶极子波的产生适合的过程中有效地耦合单量子的光和物质在自由空间。我们采用抛物面镜的横向光束模式的转换为一个集中的偶极波，并显示所需的空间和时间整形的模式入射到镜子上。结果包括一个证明的原则校正抛物面镜的像差。对于用单光子脉冲激发原子的应用，我们证明了一个合适的时间脉冲包络的创建。我们推断耦合强度的89%和成功的概率高达87%的应用程序，激发一个单一的原子为当前的实验参数。
We demonstrate the generation of an optical dipole wave suitable for the process of efficiently coupling single quanta of light and matter in free space. We employ a parabolic mirror for the conversion of a transverse beam mode to a focused dipole wave and show the required spatial and temporal shaping of the mode incident onto the mirror. The results include a proof of principle correction of the parabolic mirror’s aberrations. For the application of exciting an atom with a single photon pulse, we demonstrate the creation of a suitable temporal pulse envelope. We infer coupling strengths of 89% and success probabilities of up to 87% for the application of exciting a single atom for the current experimental parameters.
