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 is a common dopant in various solid-state laser crystals, including yttrium orthovanadate (Nd:YVO 4), yttrium lithium fluoride and yttrium aluminium garnet . All these lasers can produce high powers in the infrared spectrum at 1064 nm.
Xenotime, a REE phosphate, is the main HREE ore containing as much as 60% yttrium as yttrium phosphate (YPO 4). [56] This applies to xenotime-(Y). [61] [64] [60] The largest mine is the Bayan Obo deposit in China, making China the largest exporter for HREE since the closure of the Mountain Pass mine in the 1990s. [56] [58]
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: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 ...
Red (635 nm), blueish violet (445 nm), and green (520 nm) laser pointers. A laser pointer or laser pen is a (typically battery-powered) handheld device that uses a laser diode to emit a narrow low-power visible laser beam (i.e. coherent light) to highlight something of interest with a small bright colored spot.
