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 ...
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:

Green DPSSLs are usually around 20% efficient, although some lasers can reach up to 35% efficiency. In other words, a green DPSSL using a 2.5 W pump diode would be expected to output around 500-900 mW of 532 nm light. In optimal conditions, Nd:YVO 4 has a conversion efficiency of 60%, [1] while KTP has a conversion efficiency of 80%. [2]
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 ...
In accordance with federal law, all power-assisted bicycles, regardless of province, must 1) have a maximum of three wheels; 2) have steering handlebars and pedals; 3) use an electric motor of 500 W output or less for propulsion; 4) must not be capable of speeds faster than 32 km/h (20 mph) on level ground using motor power alone; and 5) bear a ...
Alexis Spectral Data is a software developed for colour matching processes that calculates from available spectral data the colour numbers used by computers to display colours on screen. It displays the colour for each spectral reflectance curve and records the calculated trichromatic values and colour numbers along with the spectral curves.
The S-3D, produced between 1970 and 1997, was a twin-seat, four-wheeled cyclecar, 2.6 metres (102.4 in) in length, but rather heavy (≈500 kg) due to all-steel body. It was powered by IZH-P3 air-cooled two-stroke engine (18 DIN hp).
