Nd: YVO4 Crystal
Nd: YVO4 (Neodymium-doped Yttrium Vanadate) waa mid ka mid ah sheyga ugu wanaagsan ee ganacsi ahaan laga heli karo ee loogu talagalay lasers-adag-ka-riix-riixa adag ee dawlad-goboleed, khaasatan kuwa dharka jilicsan ama hooseeya. Tusaale ahaan, Nd: YVO4 ayaa ka fiican doorashada Nd: YAG abuurista laydhadhka awoodda hoose ee tilmaamayaasha gacanta lagu hayo ama kuwa kale ee la isku haysto. Codsiyadaan, Nd: YOV4 wuxuu leeyahay xoogaa faa iido ah Nd: YAG, tusaale ahaan maqnaanshaha sare ee dareeraha leysarka laser-ka iyo qeyb weyn oo isugeyn ah oo isugeyn ah.
Nd: YVO4 waa doorashada ugu wanaagsan ee soosaarka aadka u baahsan ee 1342 nm, maaddaama qulqulaya qulqulayaashu ay aad uga xoog badan yihiin kuwa beddelka ah. Nd: YVO4 awood u leh inuu la shaqeeyo qaar ka mid ah kiristaalo aan toos ahayn oo leh NLO sareeya (LBO, BBO, KTP) si uu uga soo saaro nalalka ka soo dhowaada curyaamiinta illaa cagaarka, buluuga, ama xitaa UV.
Nagala soo xiriir xalka ugu fiican ee dalabkaaga Nd: YVO4 kiristaalo.

Faa'iidooyinka Nd: YVO4 (marka la barbar dhigo Nd: YAG)
• Xadhig ballaadhan oo xawaare ku dhawaad 808 nm ah (5 jeer ayaa laga soo qaatay Nd: YAG)
• Weynaanta waaweyn ee kicinta isgoyska 1064nm (3 jeer ka mid ah Nd: YAG)
• Xaddiga burburka laser-ka oo hooseeya iyo hufnaanta dhaadheer
• Ka duwan Nd: YAG, Nd: YVO4 waa garaac aan caadi ahayn oo si toos ah u siiya hawada isku-dhiibka ah, kana fogaanaya isku-buuq badan oo kuleylka sababay.
