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:
A rainbow is a decomposition of white light into all of the spectral colors. Laser beams are monochromatic light, thereby exhibiting spectral colors. A spectral color is a color that is evoked by monochromatic light, i.e. either a spectral line with a single wavelength or frequency of light in the visible spectrum, or a relatively narrow spectral band (e.g. lasers).
When pointed at many white objects (such as white paper or white clothes which have been washed in certain washing powders) the visual appearance of the laser dot changes from violet to blue, due to fluorescence of brightening dyes. For display applications which must appear "true blue", a wavelength of 445–450 nm is required.
Spectral measurement devices are referred to as spectrometers, spectrophotometers, spectrographs or spectral analyzers. Most spectroscopic analysis in the laboratory starts with a sample to be analyzed, then a light source is chosen from any desired range of the light spectrum, then the light goes through the sample to a dispersion array ...
In March, a mother was horrified to find a pedophile symbol on a toy she bought for her daughter. Although the symbol was not intentionally placed on the toy by the company who manufactured the ...
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. [27] 150 Nd has also been used to study double ...
