Despite that, cross-relaxation is important because it enables sensitized fluorescence, which is useful when emitting ions can't absorb the excitation light. Gain media is therefore co-doped with another type of lanthanide ions, which absorb the excitation light and transfer the electronic excitation to the ions, which produce fluorescence. This kind of gain media is used in solid-state lasers and optical fiber amplifiers</dc:description><dc:description xml:lang="sl">Elektrostatična interakcija med električnimi dipolnimi momenti lantanidnih ionov omogoča križno relaksacijo elektronske vzbuditve. Ta zmanjša fluorescenčni izkoristek in skrajša življenjski čas vzbujenega stanja. Kljub temu je pomembna, saj omogoča posredovano fluorescenco, ki je uporabna, če aktivni ioni ne morejo absorbirati vzbujevalne svetlobe. Ojačevalno sredstvo zato dopiramo z drugimi lantanidnimi ioni, ki absorbirajo vzbujevalno svetlobo in prenesejo elektronsko vzbuditev na primarne ione, ki nato fluorescirajo. Takšna ojačevalna sredstva uporabljamo v trdninskih laserjih in optičnih vlakenskih ojačevalnikih</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:doc-4XC7RTJP"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:doc-4XC7RTJP" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:doc-4XC7RTJP/dd2a062-07bb477f2-5439ad23-9a3-7c26c/PDF" /><edm:rights rdf:resource="http://rightsstatements.org/vocab/InC/1.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:dataProvider xml:lang="en">National and University Library of Slovenia</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:doc-4XC7RTJP/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:doc-4XC7RTJP" /></ore:Aggregation></rdf:RDF>
