Nonlinear properties of optical filters--implications for laser safety.
Laser safety filter materials must be evaluated at various levels up to the maximum irradiances likely to be encountered, since the absorber may exhibit nonlinear properties. Extreme care is necessary around short-duration lasers due to extremely high peak irradiances in the beam. This is especially true for visible and near-infrared lasers due to the high susceptibility to retinal injury for an observer.
