1. Muka kua tāpirihia ki te erbium
He huānga whenua onge te erbium, ko tōna tau ngota he 68, ā, ko tōna taumaha ngota he 167.3. Kei te pikitia te taumata pūngao hiko o te katote erbium, ā, ko te whakawhiti mai i te taumata pūngao o raro ki te taumata pūngao o runga e rite ana ki te tukanga mimiti o te mārama. Ko te huringa mai i te taumata pūngao o runga ki te taumata pūngao o raro e rite ana ki te tukanga tukunga mārama.
2. Te mātāpono EDFA
Ka whakamahia e te EDFA te muka erbium ion-dipped hei reo whakanui, e whakaputa ana i te hurihanga taupori i raro i te mārama papu. Ka whakatutukihia e ia te whakanui i te irahiko whakaohooho i raro i te whakaoho o te mārama tohu.
E toru ngā taumata pūngao o ngā katote erbium. Kei te taumata pūngao iti rawa, E1, ina kore e whakaohokia e tetahi mārama. Ina whakaohokia tonutia te muka e te pūtake rama reiti papu, ka whiwhi pūngao ngā matūriki i te āhua whenua ka huri ki te taumata pūngao teitei ake. Pērā i te whakawhiti mai i E1 ki E3, nā te mea he kore pumau te matūriki i te taumata pūngao teitei o E3, ka tere te taka ki te āhua pumau E2 i roto i te tukanga whakawhiti kore-ira. I tēnei taumata pūngao, he roa te ora o ngā matūriki. Nā te whakaoho tonu o te pūtake rama papu, ka piki haere tonu te maha o ngā matūriki i te taumata pūngao E2, ā, ka piki ake te maha o ngā matūriki i te taumata pūngao E1. Mā tēnei, ka tutuki te tohatoha hurihanga taupori i roto i te muka kua tāpirihia ki te erbium, ā, kei te wātea ngā tikanga mō te ako i te whakanui whatu.
Ina rite tonu te kaha o te pūngao photon tohu whakauru E=hf ki te rerekētanga taumata pūngao i waenga i a E2 me E1, E2-E1=hf, ka huri ngā matūriki i te āhua pumau ki te āhua whenua E1 i roto i te ahua o te irahiko whakaohooho. He ōrite te irahiko me te whakaurunga o ngā photon i roto i te tohu ki ngā photon, ā, ka nui ake te maha o ngā photon, ka huri te tohu whatu whakauru hei tohu whatu putanga kaha i roto i te muka kua tāpirihia ki te erbium, ka tutuki ai te whakanui tika o te tohu whatu.
