我们推导了非线性量子真空中电磁四波混频的耦合系数表达式。建议采用一种用于检测弹性光子-光子散射的实验装置，其中三个入射激光脉冲碰撞并产生具有新频率和传播方向的第四波。推导了散射光子数量的表达式，并使用卢瑟福阿普尔顿实验室 Astra Gemini 系统的光束参数，发现信号可以达到可检测的水平。回顾了镜头间的再现性问题，并估计了竞争散射过程产生的噪声大小。发现可以实现弹性光子-光子散射的检测。
We derive expressions for the coupling coefficients for electromagnetic four-wave mixing in the nonlinear quantum vacuum. An experimental setup for detection of elastic photon-photon scattering is suggested, where three incoming laser pulses collide and generate a fourth wave with a new frequency and direction of propagation. An expression for the number of scattered photons is derived and, using beam parameters for the Astra Gemini system at the Rutherford Appleton Laboratory, it is found that the signal can reach detectable levels. Problems with shot-to-shot reproducibility are reviewed, and the magnitude of the noise arising from competing scattering processes is estimated. It is found that detection of elastic photon-photon scattering may be achieved.
