Neodymium-doped yttrium orthovanadate (Nd:YVO 4) is a crystalline material formed by adding neodymium ions to yttrium orthovanadate. It is commonly used as an active laser medium for diode-pumped solid-state lasers. It comes as a transparent blue-tinted material. It is birefringent, therefore rods made of it are usually rectangular.
Yttrium orthovanadate (YVO 4) is a transparent crystal. Undoped YVO 4 is also used to make efficient high-power polarizing prisms similar to Glan–Taylor prisms. [1] There are two principal applications for doped yttrium orthovanadate: Doped with neodymium it forms Nd:YVO 4, an active laser medium used in diode-pumped solid-state lasers. [2]

Neodymium-doped yttrium lithium fluoride (Nd:YLF) is a lasing medium for arc lamp-pumped and diode-pumped solid-state lasers. The YLF crystal (LiYF 4 ) is naturally birefringent , and commonly used laser transitions occur at 1047 nm and 1053 nm.
Nd-doped YCOB (Nd:YCa 4 O(BO 3) 3) is a nonlinear optical crystal, which is commonly used as an active laser medium. It can be grown from a melt by the Czochralski technique . It belongs to the monoclinic system with space group C s 2 -Cm.
Nd:YAG (neodymium-doped yttrium aluminum garnet; Nd:Y 3 Al 5 O 12) is a crystal that is used as a lasing medium for solid-state lasers. The dopant , neodymium in the +3 oxidation state, Nd(III), typically replaces a small fraction (1%) of the yttrium ions in the host crystal structure of the yttrium aluminum garnet (YAG), since the two ions are ...
Neodymium also has 15 known metastable isotopes, with the most stable one being 139m Nd (t 1/2 = 5.5 hours), 135m Nd (t 1/2 = 5.5 minutes) and 133m1 Nd (t 1/2 ~70 seconds). The primary decay modes before the most abundant stable isotope, 142 Nd, are electron capture and positron decay , and the primary mode after is beta minus decay .
The price of dysprosium oxide was US$994/kg in 2011, but dropped to US$265/kg by 2014. [ 63 ] On August 29, 2014, the WTO ruled that China had broken free-trade agreements, and the WTO said in the summary of key findings that "the overall effect of the foreign and domestic restrictions is to encourage domestic extraction and secure preferential ...
