Paper Abstract

Both the increasing use of laser devices on the battlefield and the misuse of laser devices in civil environments (e.g. dazzling of pilots during approach) necessitate laser protection devices. Conventional laser protection filters based on absorption or interference effects only work in narrow wavelength bands and are usually not neutral in colour. Thus, they are not appropriate for such scenarios. Optical power limiting devices based on nonlinear optical effects (nonlinear absorption, nonlinear refraction, induced scattering) were proposed to offer broadband laser protection without disturbing the visual colour impression. Usually, optical nonlinear materials are examined in laboratory setups which are different from realistic optical systems. We report on the integration of nonlinear laser protection devices into different optical systems to prove the performance of limiting for commonly used optical systems.
