Laser detection phosphors are used to detect the presence of laser beams in the infrared region by converting the energy to visible light. These phosphors are separated into two types.
Storage phosphors react to a broad spectrum of infrared, but require daylight or ultraviolet light to charge up the phosphor first. Exposure to infrared will cause the stored energy to be released as visible light. The output will gradually drop though as the stored energy is depleted.
Anti-Stokes phosphors are designed for up-conversion of the infrared to visible light. The process involves the energy from two or three photons combining. A single photon with higher energy than the absorbed photons is then emitted. Unlike storage phosphors, the light output has a consistent intensity but the excitation range is much narrower.
Our standard ranges of phosphors for these two different types are listed below. For specific requirements not listed here, please contact us.
