摘要：

在背景如外部磁场或非对易时空中，线偏振光通过前向康普顿散射可以部分地转变为圆偏振光。基于这一事实，我们探讨了NC背景对线偏振激光束与强流带电轻子束散射的影响。我们表明，μ子/电子束流$\bar\varepsilon_{μ,e}\sim 10^{12}/10^{10}\,{\rm TeV}\,{\rm cm}^{-2}\,{\rm sec}^{-1}$和线偏振激光束的能量$k^0\sim $ 1 eV和平均功率$\bar{P}_{\rm laser}\simeq$ 1 MW，圆偏振光的产生率约为$R_{_V} \sim 10^4/{\rm sec}$的非对易能量标度$Λ_{\tiny{NC}}\sim 10$ TeV。这是相当大的，可以在不久的将来增长更强的光束。

英文摘要：

It is known that the linearly polarized photons can partly transform to circularly polarized ones via forward Compton scattering in a background such as the external magnetic field or noncommutative space time. Based on this fact we explore the effects of the NC-background on the scattering of a linearly polarized laser beam from an intense beam of charged leptons. We show that for a muon/electron beam flux $\bar\varepsilon_{μ,e}\sim 10^{12}/10^{10}\,{\rm TeV}\,{\rm cm}^{-2}\,{\rm sec}^{-1}$ and a linearly polarized laser beam with energy $k^0\sim $1 eV and average power $\bar{P}_{\rm laser}\simeq$1 MW, the generation rate of circularly polarized photons is about $R_{_V} \sim 10^4/{\rm sec}$ for Noncommutative energy scale $Λ_{\tiny{NC}}\sim 10$TeV. This is fairly large and can grow for more intense beams in near future.
