We present a concept of a whitelightseededcascaded midinfrared (midIR) optical parametric amplifier (OPA) based on potassium titanyl arsenate and zinc germanium phosphate nonlinear optical crystals and producing 100μJ level pulses centered at 5300 nm, with the spectrum supporting fouropticalcycle pulse duration. The OPA is pumped by 2090nm master oscillator/power amplifier based on a ...

Germanium (Ge) is a graywhite element known as a semimetal. It has an atomic number of thirtytwo and has a high luster at room temperature. Germanium is another element that was predicted by Mendeleev in 1871. His predictions for what would be the atomic number, weight, and .

Thorlabs' Precision Germanium (Ge) Windows are offered in Ø1/2 and Ø1 sizes. They are available uncoated or with an AR coating on both sides that provides <2% average reflectance from to 6 µm (offered in Ø1 size only) or <1% average reflectance from 7 to

The germanium Grignard reagent reacts with various primary and secondary alkyl electrophiles by an ionic nucleophilic displacement. Conversely, the coupling of the corresponding zinc reagent requires a nickel catalyst, which then engages in radical bond formations .

Germanium is mainly a byproduct of zinc ore processing. It is a hard, grayishwhite element; it has a metallic luster and the same crystal structure as diamond; and it is brittle, like glass. In addition, it is important to note that germanium is a semiconductor, with electrical properties between those of a .

Germanium, a chemical element between silicon and tin in Group 14 (IVa) of the periodic table, a silverygray metalloid, intermediate in properties between the metals and the nonmetals. It did not become economically significant until after 1945, when its properties as a .

Germanium and germanium oxide are transparent to the infrared and are used in infrared spectroscopes and other optical equipment, including extremely sensitive infrared detectors. The high index of refraction and dispersion properties of its oxide's have made germanium useful as a component of wideangle camera lenses and microscope objectives.

Zinc has the element symbol Zn and atomic number 30, making it a transition metal and the first element in Group 12 of the periodic table. Sometimes zinc is considered to be a posttransition metal. The element name is believed to come from the German word "zinke," which means "pointed." This is likely a reference to the pointed zinc crystals that form after zinc is smelted.
