ABSTRACT:
An optical power limiter is designed for use with high gain optical systems by providing intensity reduction by the use of a non-linear fluid. As the intensity of light increases in the fluid, the index of refraction becomes non-linear very rapidly. This results in a plasma being formed within the fluid. Picosecond reaction time is provided. Recovery time of less than a microsecond is required for the system to return to its starting point.
