Abstract
We have measured the stabilized coloration produced from the conversion of centers in KCl by means of a two-photon process. The measurements show that the coloration involves energy transfer via electron-hole pairs, rather than direct photoexcitation of the centers. The absolute two-photon absorption cross section of KCl at nm was determined.
