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: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 ...
One of the most common classifications divides REE into 3 groups: light rare earths (LREE - from 57 La to 60 Nd), intermediate (MREE - from 62 Sm to 67 Ho) and heavy (HREE - from 68 Er to 71 Lu). REE usually appear as trivalent ions, except for Ce and Eu which can take the form of Ce 4+ and Eu 2+ depending on the redox conditions of the system ...

The OMG Decision Model and Notation standard is designed to standardize elements of business rules development, specially decision table representations. There is also a standard for a Java Runtime API for rule engines JSR-94. OMG Business Motivation Model (BMM): A model of how strategies, processes, rules, etc. fit together for business modeling
