Potera, Piotr2014-10-292014-10-292012http://repozytorium.ur.edu.pl/handle/item/547The transient and stable color centers in pure and doped lithium niobate crystals (LNO) have been investigated in several works, for example in [1]. The stable color centers are centers which have lifetime higher then 1s. Unfortunately, the lifetime of color centers were studied in literature only for transient color centers, for example in [2]. In this work the lifetime of stable additional absorption induced by gamma irradiation in Cu doped of LNO crystal will be determined from data obtained during 10 years.engUznanie autorstwa-Użycie niekomercyjne-Bez utworów zależnych 3.0 Polskahttp://creativecommons.org/licenses/by-nc-nd/3.0/pl/gamma irradiationcolor centersconferenceObject
