Nd: YVO4 Crystal
Nd: YVO4 (Neodymium-doped Yttrium Vanadate) bụ otu n'ime akụrụngwa azụmahịa kachasị mma maka lasers diode-pump siri ike, ọkachasị ndị lasers nwere nnukwu ume ma ọ bụ nke etiti. Iji maa atụ, Nd: YVO4 bụ nhọrọ dị mma karịa Nd: YAG maka imepụta obere ike dị na ntinye aka ma ọ bụ usoro lacers ndị ọzọ. N'ime ngwa ndị a, Nd: YOV4 nwere uru ufodu na Nd: YAG, dika nnabata nnuku nke laser pumped na nke ukwu riri.
Nd: YVO4 Nke a bụ ezigbo nhọrọ maka mmepụta polarized dị ukwuu na 1342 nm, ebe eriri ementi siri ike karịa nke ndị ọzọ. Nd: YVO4 nwere ike ịrụ ọrụ na ụfọdụ kristal ndị na-adịghị elu na ọnụọgụ NLO dị elu (LBO, BBO, KTP) iji wepụta ọkụ site na nso infrared ruo akwụkwọ ndụ akwụkwọ ndụ, acha anụnụ anụnụ, ma ọ bụ ọbụna UV.
