If you do not find the ideal products previously mentioned, you might allow us to know your necessities or purposes in the shape below. Our sales or specialized staff will get back to you at the earliest opportunity.
Inertness to Moisture: BIBO crystal is inert to humidity, meaning it doesn't degrade or shed its optical Qualities when subjected to humidity. This tends to make BIBO a far more stable and reputable option for optical applications in a variety of environments.
The vast majority of common nonlinear crystals like BBO, LBO, BiBO or KTP for frequency doubling, tripling and quadrupling of the fundamental laser radiation can be obtained from stock. Consumer-distinct dimensions and AR coatings will also be provided at competitive prices.
Normally, the crystal material should have a high optical transparency for all wavelengths involved �?for instance, for pump, signal and idler within an optical parametric amplifier.
Artifex Engineering offers concluded crystal optics for non-linear apps. Check out our solution page For more info. We sit up for your inquiry.
Although the crystal product or coating isn't sensitive to water, modest water droplets might concentrate laser radiation a lot more tightly than underneath standard Procedure, and thus destruction the crystal materials.
Lithium niobate (LiNbO3) and lithium tantalate (LiTaO3) are elements with a comparatively potent nonlinearity. They are sometimes useful for nonlinear frequency conversion in addition to for electro-optic modulators. Each resources can be found in congruent and in stoichiometric form, with significant variances about periodic poling and photorefractive outcomes (see down below). Lithium niobate and tantalate would be the most often utilized elements from the context of periodic poling; the ensuing elements are termed PPLN (periodically poled lithium niobate) and PPLT, respectively, or PPSLN and PPSLT with the stoichiometric variations.
Bismuth Triborate (BiB3O6 or BIBO) is a newly produced nonlinear optical crystal. It possesses substantial effective nonlinear coefficient, significant destruction threshold and inertness with respect to moisture.
They exhibit very good homogeneity over massive volumes and possess a higher damage threshold, but are hygroscopic and also have a small nonlinearity.
Many various properties of the nonlinear crystal can be essential for an application e.g. in nonlinear frequency conversion:
In many conditions, a nonlinear crystal useful for nonlinear frequency conversion has an exceptionally long life span, which can be for a longer time than that of The full laser procedure. The crystal substance is actually not modified all through Procedure. However, a reduced crystal life span can happen under several circumstances:
芯飞睿所有的服务和支持都立足于使我们的客人工作的更加高效，更有价值。
The magnitude of the helpful nonlinear coefficient relies on the nonlinear tensor factors and within the utilized stage-matching configuration. A higher nonlinearity is essential particularly if the achievable optical intensities are reduced.
Given that the 2nd harmonic (SHG) might be extensively utilized to make coherent visible gentle and ultraviolet radiation, folks listen to it, but the standard nonlinear crystals like KDP, LBO, KTP, B-BBO even have numerous shortcomings. BIBO crystal is a completely new form of nonlinear crystal. Compared with KDP crystal, it would make up for your drawback that KDP crystal can grow in substantial dimension read more but dissolve in drinking water.
