In particular, it is possible to determine the center creation intensity threshold and therefore to discuss the basic formation mechanisms of these centers.318-321openAccesscolor centerscrystalslithium fluoridespulseswaveguidesyttrium fluoridesArtigo de periódico122-12310.1016/j.jlumin.2006.01.157https://orcid.org/0000-0003-0092-9357https://orcid.org/0000-0002-5018-9126https://orcid.org/0000-0001-7762-8961
