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:

The governor of Illinois has the power to veto proposed congressional district maps, but the General Assembly has the power to override the veto, with the support of 3/5ths of both chambers. In 1971, 1981, and 1991, the General Assembly was unable to come to an agreement, and the map was drawn up by a panel of three federal judges chosen by ...

Blue DPSSLs use a nearly identical process, except that the 808 nm light is being converted by an Nd:YAG crystal to 946 nm light (selecting this non-principal spectral line of neodymium in the same Nd-doped crystals), which is then frequency-doubled to 473 nm by a beta barium borate (BBO) crystal or LBO crystal. Because of the lower gain for ...
[13] [31] One specific REE of interest is neodymium (Nd), which has extensive applications in the industry. [13] Nd exhibits distinctive spectral features in reflectance spectroscopy that can be used for its detection and identification, centred near 740, 800, and 865 nm (D 740, D 800, D 865) in the wavelength spectra.
Illinois's 9th House of Representatives district is a Representative district within the Illinois House of Representatives located in Cook County, Illinois. It has been represented by Democrat Yolonda Morris since 2023. Before then it was Lakesia Collins since July 24, 2020. The district was previously represented by Democrat Art Turner from ...
