If you do not locate the suited products and solutions earlier mentioned, you could allow us to know your requirements or purposes in the form under. Our product sales or technical employees can get back again for you right away.
In addition it has a vital software in efficient generation of ultrabright entangled photons by way of blue pumped spontaneous parametric down conversions (SPDC).
The vast majority of regular nonlinear crystals like BBO, LBO, BiBO or KTP for frequency doubling, tripling and quadrupling of the basic laser radiation can be obtained from inventory. Shopper-precise dimensions and AR coatings may also be presented at aggressive selling prices.
Generally, the crystal material should have a high optical transparency for all wavelengths involved �?one example is, for pump, sign and idler in an optical parametric amplifier.
BIBO crystals may be used as superior-performance frequency doubling and frequency summing products and also have broad software prospective buyers in optical parametric oscillation (OPO).
GWU-Lasertechnik has a lot more than thirty a long time of practical experience in distributing laser crystals. Opt for GWU to take pleasure in our huge information and in-discipline working experience!
Lithium niobate (LiNbO3) and lithium tantalate (LiTaO3) are materials with a relatively potent nonlinearity. They are often utilized for nonlinear frequency conversion and in addition for electro-optic modulators. Equally supplies are available in congruent and in stoichiometric variety, with significant discrepancies regarding periodic poling and photorefractive results (see beneath). Lithium niobate and tantalate would be the most often utilised products during the context of periodic poling; the ensuing elements are called PPLN (periodically poled lithium niobate) and PPLT, respectively, or PPSLN and PPSLT for the stoichiometric versions.
Crylink is undoubtedly an open up platform, just as our mission is to attach price, Crylink believes that every individual and each enterprise has special worth, and we hope to connect with precious you to provide value and replicate price collectively.
They show great homogeneity in excess of big volumes and have a high injury threshold, but are hygroscopic and also have a very low nonlinearity.
Crystals which might be non-critically section-matched within a crystal oven may perhaps exhibit troubles when the crystal temperature is adjusted way too promptly or as well usually. Especially, anti-reflection coatings could be destroyed as a result of distinctive thermal enlargement coefficients of the associated resources.
Bismuth Triborate (BiB3O6 or BIBO) can be a freshly developed nonlinear optical crystal. It possesses substantial successful nonlinear coefficient, substantial damage threshold and inertness with respect to humidity.
China BIBO crystals can be used not merely as large-efficiency frequency doubling and frequency summing products, but also have broad software potential clients in the field of optical parametric oscillation (OPO), and In addition it has a vital application during the effective era of ultrabright entangled photons via blue pumped Spontaneous Parametric Down Conversions (Also Know as SPDC).
linear absorption, that may induce heating at large optical electric power concentrations, so that the phase matching is disturbed, and thermal lensing may arise
Because the 2nd harmonic (SHG) is usually widely used to create coherent seen gentle and ultraviolet radiation, people pay attention to it, but the traditional nonlinear crystals including KDP, LBO, KTP, B-BBO also have many shortcomings. BIBO crystal is a fresh style of nonlinear crystal. As opposed with KDP click here crystal, it will make up for the downside that KDP crystal can mature in large sizing but dissolve in drinking water.
