As in all neodymium-doped laser crystals, the lasing action of Nd:YVO 4 is due to its content of neodymium ions, which may be excited by visible or infrared light, and undergo an electronic transition resulting in emission of coherent infrared light at a lower frequency, usually at 1064 nm (other transitions in Nd are available, and can be ...
[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] Doped with europium it forms Eu:YVO 4, the dominant red phosphor used in cathode-ray tubes especially in color TVs. [3]

146 Nd has been suggested for the production of 147 Pm, which is a source of radioactive power. Several neodymium isotopes have been used for the production of other promethium isotopes. The decay from 147 Sm (t 1/2 = 1.06 × 10 11 y) to the stable 143 Nd allows for samarium–neodymium dating. [28] 150 Nd has also been used to study double ...
The number of adults eating in a way they consider to be healthy has fallen, according to new data. What’s more, research shows they aren’t enjoying the food either.
Mitja Kobal/GETTY IMAGES. 2. Go Stargazing. Astronomy is one of the most fascinating and magical subjects, and stargazing is an undeniably romantic hobby and a good place to start if you and your ...
Multiple studies have assessed these relationships in the past, but findings were mixed or limited in geographical scope, the authors said — so they analyzed more than 1.7 million suicides in ...
[1] Titanium-sapphire refers to the lasing medium, a crystal of sapphire (Al 2 O 3) that is doped with Ti 3+ ions. A Ti:sapphire laser is usually pumped with another laser with a wavelength of 514 to 532 nm, for which argon-ion lasers (514.5 nm) and frequency-doubled Nd:YAG, Nd:YLF, and Nd:YVO lasers (527–532 nm) are used.
