Nd: YVO4 Crystal
Nd: YVO4 (Neodymium-doped Yttrium Vanadate) o se tasi o sili sili ona lelei avanoa faʻapisinisi mea mo diode-pamu mautu-tulaga lasers, aemaise mo lasers ma maualalo pe ogatotonu mana malosi. Mo se faʻataʻitaʻiga, Nd: YVO4 o se filifiliga sili atu nai lo Nd: YAG mo le gaosia o le maualalo-mana utupoto i lima-faʻailo lima poʻo isi lasers pu. I totonu o nei talosaga, Nd: YOV4 O loʻo iai ni tulaga lelei i luga ole Nd: YAG, faʻataʻitaʻiga o le maualuga o le faʻaaogaina o le faʻasaina o le laser iradiation ma le faʻaosofia tele o faʻasalalauga vaega.
Nd: YVO4 o se lelei filifiliga mo maualuga polarized i 1342 nm, ona o le laina faʻapaologa e sili malosi nai lo i latou o ona isi filifiliga. Nd: YVO4 e mafai ona galue ma nisi nonlinear tioata ma maualuga NLO coefficient (LBO, BBO, KTP) e maua ai moli mai latalata infrared i lanumeamata, lanumoana, pe oʻo foi i le UV.
Faʻafesoʻotaʻi mai matou mo le fofo sili mo lau talosaga Nd: YVO4 alamanuia.
