Nd: Crystal YVO4
Nd: YVO4 (Neodymium-doped Yttrium Vanadate) ndi imodzi mwazinthu zabwino kwambiri zogulitsa ma diode-pumped solid-state lasers, makamaka kwa ma lasers okhala ndi mphamvu yotsika kapena yapakati. Mwachitsanzo, Nd: YVO4 ndikusankha kwabwinoko kuposa Nd: YAG yopanga timapanga tating'onoting'ono tating'ono tating'ono tating'ono tating'ono tating'onoting'ono tating'ono tating'ono tating'ono kapena ma septure ena opindika. M'maguluwa, Nd: YOV4 ili ndi maubwino ena pa Nd: YAG, mwachitsanzo, mayamwidwe okweza a laser komanso zida zazikulu zodutsa.
Nd: YVO4 ndichisankho chabwino pakupanga koyenera kwambiri pa 1342 nm, chifukwa mzere woperekawo ndi wamphamvu kwambiri kuposa njira zina zake. Nd: YVO4 imatha kugwira ntchito ndi makristali ena osakhudzana ndi makementi apamwamba a NLO (LBO, BBO, KTP) kuti apange magetsi kuyambira pafupi ndi infrared mpaka kubiriwira, buluu, kapena ngakhale UV.
Lumikizanani nafe kuti mupeze yankho lanu labwino kwambiri pa Nd: YVO4 makhiristo.

Ubwino wa Nd: YVO4 (ndikuyerekeza ndi Nd: YAG)
• Kuthambalala kwakatundu pafupi 808 nm (kangapo kwa Nd: YAG)
• Zachikulu zazikulu zodutsa pamtanda pa 1064nm (katatu katatu kwa Nd: YAG)
• Pazowonongeka pang'ono zowonongeka za laser ndikuthamanga kwambiri
• Osiyana ndi Nd: YAG, Nd: YVO4 ndi galasi la uniaxial lomwe limapatsa utoto wowoneka bwino, kupewa kupewa kulumikizana kwambiri.
