Nd: Crystal ea YAG
Nd: YAG (Neodimium Doped Yttrium Aluminium Garnet) esale ebile e ntse e tsoela pele ho ba kristale ea laser e sebelisoang ka ho fetesisa bakeng sa lasers tse tiileng tsa 'muso. Nako e ntle ea fluorescence (e habeli ho feta ea Nd: YVO)4) le conducction ea mafura, le tlhaho e matla, e etsa hore Nd: Kristale ea YAG e loketse haholo ts'ebetso ea matla a phahameng a ts'oarehang, Q-switched e matla le ts'ebetso ea mode e le 'ngoe.
WISOPTIC e fana ka Nd: lithupa tsa YAG li na le lintlha tse latelang: maemo a fapaneng a doping, homogeneity e phahameng ea sefahleho, ho nepahala ha ts'ebetso e phahameng, li-barbar tse otlolohileng le li-angle tsa wedge, likhahla tse fapaneng tsa ho felisoa, liaparo tse fapaneng tsa dielectric, ho senya haholo.
