摘要:

本文讨论了迄今为止用于测量真空中强横向磁场产生的激光偏振态变化的实验技术。我们指出了可能出现的文物,在这样的实验中,特别是最近的PVLAS观测和以前的研究结果的BFRT合作。我们的观测是基于光子噪声限制相干零差干涉仪的研究,该干涉仪的偏振灵敏度为2 × 10 ^-8 rad Hz^(1/2)mW^(-1/2)。

英文摘要:

We discuss the experimental techniques used to date for measuring the changes in polarization state of a laser produced by a strong transverse magnetic field acting in a vacuum. We point out the likely artifacts that can arise in such experiments, with particular reference to the recent PVLAS observations and the previous findings of the BFRT collaboration. Our observations are based on studies with a photon-noise limited coherent homodyne interferometer with a polarization sensitivity of 2x10^-8 rad Hz^(1/2) mW^(-1/2).
