The 2-Minute Rule for BIBO Crystal
The 2-Minute Rule for BIBO Crystal
Blog Article
Hygroscopic crystal elements deteriorate when they are not generally saved in adequately dry air (or possibly a dry purge gasoline). This is applicable e.g. to KDP and BBO, and in a lesser extent to LBO. It can be handy to keep this type of crystal at a considerably elevated temperature, which makes it simpler to maintain it dry.
Furthermore, it has a crucial application in effective generation of ultrabright entangled photons as a result of blue pumped spontaneous parametric down conversions (SPDC).

Artifex Engineering provides concluded crystal optics for non-linear apps. Pay a visit to our item page To learn more. We anticipate your inquiry.
Applying our advertising and marketing package deal, you can Exhibit your emblem, additional under your products description, and these will been noticed by many photonics gurus.
Observe that regardless of whether the nominal depth is under the nominal harm threshold, there may be complications resulting from fluctuations while in the beam electrical power or nearby depth (e.g., if a beam profile has “incredibly hot spots�?, or due to isolated defects inside of a crystal, which might be a lot more delicate in comparison to the typical crystal material.
Procedure of nonlinear crystals at temperatures under space temperature (to achieve section matching) is normally problematic, as it might bring about condensation of water over the crystal surfaces If your encompassing air just isn't very dry.
In read more the situation of ultrashort pulses the substantial team velocity mismatch enforces the usage of a shorter crystal, which calls for significant optical intensities for your supplied conversion performance.
Excessive optical intensities throughout operation may instantly damage a crystal. Unfortunately, nonlinear crystals normally should be operated not significantly from their optical hurt threshold to realize a sufficiently high conversion performance. This means a trade-off among conversion efficiency and crystal life span.
Bismuth Triborate (BiB3O6 or BIBO) is often a recently formulated nonlinear optical crystal. It possesses large efficient nonlinear coefficient, substantial problems threshold and inertness with regard to dampness.
GWU-Lasertechnik offers all normal nonlinear crystals like LBO, BBO and KTP having a wide number of technical specs. Beside the well-recognized elements, progressive crystals like CLBO or BiBO with excellent properties for e. g. deep-UV generation or large-electrical power ultrashort pulse lasers are offered. Regardless of if particular person pieces for R & D purposes are needed or cost-effective numbers in tiny, medium or large batches with in-time supply to the generation line are necessary: GWU’s committed assistance helps to find the most effective core parts for your application.
Optical crystals can show unique sorts of optical nonlinearities, which may be used in a variety of methods:
Our crystals are Utilized in a variety of purposes, such as various styles of nonlinear frequency conversion and electro-optics, but in addition quantum engineering.
