Abstract
Collimated incident optical radiation which might contain high-intensity or igh-power radiation is focused into the body of a limiter by a first lens formed at one end of the limiter. The body is a cylinder of revolution with an axis along the optical axis between radiation and a sensitive detector. Radiation of normal intensity or power freely passes through the body and is recollimated by a second lens formed at the other end of the limiter from the first lens. The body is made of material which is subject to two-photon absorption such that high-intensity or high-power radiation undergoes absorption and is consequently self-defocused such that it is diverted from the optical path. For visible light, the material may be ZeSe or ZnS; for ultraviolet, copper chloride; for infrared, HgCgTe.
