真空中混合过程的检测方案

Scheme for the detection of mixing processes in vacuum

F. Fillion-Gourdeau, C. Lefebvre, S. MacLean

摘要:

提出了一种探测真空混合过程产生的光子的方案。该策略包括利用高数值孔径的抛物柱面镜,其紧密聚焦具有不同频率的两个共同传播的激光束。这在焦点附近产生非常高强度的区域,其中光子-光子非线性相互作用然后可以通过波混合过程诱导新的电磁辐射。这些过程进行了理论研究。焦点处的场由Stratton-Chu矢量衍射理论获得,该理论可以适应入射激光束的任何配置。对于入射的径向偏振光束,评估所生成的光子的数量。它表明,使用这种场配置,真空混合过程中可以检测到设想的激光技术。

英文摘要:

A scheme for the detection of photons generated by vacuum mixing processes is proposed. The strategy consists in the utilization of a high numerical aperture parabolic mirror which tightly focuses two co-propagating laser beams with different frequencies. This produces a very high intensity region in the vicinity of the focus, where the photon-photon nonlinear interaction can then induce new electromagnetic radiation by wave mixing processes. These processes are investigated theoretically. The field at the focus is obtained from the Stratton-Chu vector diffraction theory, which can accomodate any configuration of an incoming laser beam. The number of photons generated is evaluated for an incident radially polarized beam. It is demonstrated that using this field configuration, vacuum mixing processes could be detected with envisaged laser technologies.
