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: Doped with neodymium it forms Nd:YVO 4, an active laser medium used in diode-pumped solid-state lasers. [2]
Neodymium-doped yttrium lithium fluoride (Nd:YLF) is a lasing medium for arc lamp-pumped and diode-pumped solid-state lasers. The YLF crystal (LiYF 4 ) is naturally birefringent , and commonly used laser transitions occur at 1047 nm and 1053 nm.
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 ...
Red (635 nm), blueish violet (445 nm), and green (520 nm) laser pointers. A laser pointer or laser pen is a (typically battery-powered) handheld device that uses a laser diode to emit a narrow low-power visible laser beam (i.e. coherent light) to highlight something of interest with a small bright colored spot.
The European Union allows residents of member states to seek refunds for goods and services purchased outside of a shop, such as by telephone, mail order or in response to a door-to-door sales pitch, to cancel the transaction, return any purchase and obtain a refund within fourteen days.
A pattern day trader is generally defined in FINRA Rule 4210 (Margin Requirements) as any customer who executes four or more round-trip day trades within any five successive business days. [3] FINRA Rule 4210 is substantially similar to New York Stock Exchange Rule 431. [4]
The rule provided that upon acquiring 30% of the outstanding common stock of the target, the acquirer must make a bid for all remaining outstanding shares within 45 working days, at a price which at least matches the highest price paid by the acquirer in the past year for the shares it already holds, as well as the average market price of the ...
