Nd: YVO4 Crystal
Nd: YVO4 (I-Neodymium-doped Yttrium Vanadate) yenye yezona zixhobo zihle kakhulu zentengiso zerode di-pumped solid-state lasers, ngakumbi ii-lasers ezinamandla asezantsi okanye aphakathi amandla. Umzekelo, Nd: YVO4 lukhetho olungcono kuneNd: I-YAG yokuvelisa amandla asezantsi kwizibane eziphethwe ngesandla okanye kwezinye iicactact lasers. Kwezi zicelo, Nd: YOV4 unezinzuzo ezithile ngaphezulu kwe-Nd: i-YAG, umz. ukufakwa okuphezulu kwemithombo ye-laser epumileyo kunye necandelo lomnqamlezo omkhulu wokuhambisa.
Nd: YVO4 lukhetho olufanelekileyo lokuveliswa kwePolarized kakhulu kwi-1342 nm, njengoko umgca wokukhupha unamandla ngakumbi kuneendlela ezizezinye. Nd: YVO4 Iyakwazi ukusebenza ngeekristali ezinganqwenelekiyo ezinee-NLO eziphezulu (LBO, BBO, KTP) ukuvelisa izibane ukusuka kufutshane ne-infrared ukuya eluhlaza, luhlaza, okanye i-UV.
Nxibelelana nathi malunga nesisombululo esona sisicelo sakho seNd: YVO4 amakristali.
