Optical limitation in resonant Faraday media sandwiched between crossed polarizers is analyzed both theoretically and experimentally. In this technique resonant Faraday rotation permits a net transmission at low intensity levels, whereas the setup transmission is quenched at higher intensities when the active transition is completely saturated. This technique offers many advantages, such as a very low fluence threshold (~12 nJ/cm(2) in cesium vapor), a high intensity range (more than 4 orders of magnitude for polarizer losses of 10(-5)), and quasi invulnerability to optical damage, which make this technique attractive for the protection of fixed-wavelength operated detectors.
对夹在交叉偏振器之间的共振法拉第介质中的光学限制进行了理论和实验分析。在该技术中，共振法拉第旋转允许在低强度水平下有净透射，而当激活跃迁完全饱和时，在较高强度下装置透射会被猝灭。该技术具有许多优点，例如极低的能量密度阈值（铯蒸汽中约为12 nJ/cm²）、高强度范围（对于10⁻⁵的偏振器损耗超过4个数量级）以及对光学损伤的准免疫性，这些使得该技术对于保护固定波长工作的探测器具有吸引力。
