In 1974, the first such experiment was carried out by Clauser, who reported a violation of a classical Cauchy–Schwarz inequality. In 1977, Kimble ''et al.'' demonstrated an analogous anti-bunching effect of photons interacting with a beam splitter; this approach was simplified and sources of error eliminated in the photon-anticorrelation experiment of Grangier ''et al.

尽管到了二十世纪七十年代支持光子说的物理和化学实验依据已经相当丰富，证据可能还是不能被认为绝对确凿；因为这些实验都依赖于光与物质的相互作用，而一个足够复杂的关于物质的量子力学理论则仍然有可能去解释这些实验现象。

This attribute can greatly reduce the size of your caustic photon map.

这个属性可以极大的减少你的焦散光子贴图的大小。

It is found that the expansion width of the circular frequency optical spectrum of the scattered photons in multiphoton nonlinear Compton effect increases with the incident electron velocity increase and the increase of the photon number by the electron absorpted at the same time,and it red...

结果表明，未被俘获电子使该散射的频谱展宽随入射电子速度和与电子同时作用的光子数的增大而增大，随电子与光子非弹性碰撞成分的增大而减小，从而使能量转换效率近乎与电子入射速度正比降低。
