Nd YAG
Na faia i le onosefulu o le seneturi talu ai, Nd: YAG sa avea ma faʻaauau pea ona avea ma tioata laser sili ona faʻaaogaina mo mea tioata malo.O ona fa'asologa o le laser o se fetuutuuna'i lelei i le va o malosiaga ma vaivaiga o lana tauvaga.Nd: YAG tioata o loʻo faʻaaogaina i ituaiga uma o lasers solid-state.Pe a faatusatusa i isi tioata leisa, o lona ola fluorescence e faaluaina nai lo Nd: YVO4, ma conductivity vevela e sili atu foi.
Fa'aaliga ma Fa'aoga
★ Maualalo gau i le 1064 nm, Maualuluga Optical Tulaga Lelei, Lelei Faʻainisinia ma Meatotino vevela
★ Maualuluga Maualuluga, Maualalo Avanoa, Maualuga Maualuga
★ Ona o le simmetry kupita ma le maualuga, Nd:YAG e faigofie ona faʻaogaina i le TEM00 mode
★ Fausia leisa lanumoana faʻatasi ma le faʻaluaina o le 946nm
★ Ia Q-sui ma Cr:YAG tuusao
★ Fa'agaioia i se leisa malosi maualuga e o'o atu i le KW

Matou te tuʻuina atu foʻi le Nd: YAG laser rods, lea e mafai ona faʻaleleia ai le lelei o le laʻau, faʻaitiitia le aʻafiaga o le vevela, ma faʻaleleia le lelei o le tootoo e 10-20%.
Mo nisi faʻamatalaga e uiga i isi ituaiga tioata e pei ole Nonlinear Crystal [BBO (Beta-BaB2O4), Potassium Titanium Oxide Phosphate (KTiOPO4 poʻo KTP)], Passive Q-Switch Crystal [Cr: YAG (Cr4 +: Y3Al5O12)], EO Crystal [ Lithium Niobate (LiNbO3), tioata BBO], Birefringent Crystal [Yttrium Orthovanadate (YVO4), Calcite, Lithium Niobate (LiNbO3), Pepa maualuga BBO (α-BaB2O4), Single Synthetic Crystal Quartz, Magnesium Fluoride (MgF2)] pe maua se upusii, faamolemole lagona le saoloto e faafesootai matou.
