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:
[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.
Goose Lake Prairie State Natural Area is a 2,537-acre (1,027 ha) state park in Illinois. More than half of the state park is a tallgrass prairie maintained as an Illinois Nature Preserve . It is located in Grundy County near the town of Morris approximately 50 miles (80 km) southwest of Chicago .

The Illinois Department of Natural Resources (IDNR) is the code department [1] [2] of the Illinois state government that operates the state parks and state recreation areas, enforces the fishing and game laws of Illinois, regulates Illinois coal mines and other extractive industries, operates the Illinois State Museum system, and oversees scientific research into the soil, water, and mineral ...
More than 30 Illinois state parks, recreation areas and wildlife areas are in the path of totality, and dozens more sites lie just outside the path and will offer quality but shorter views of the ...
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 ...
