Inertness to Moisture: BIBO crystal is inert to moisture, which implies it doesn't degrade or lose its optical Attributes when exposed to humidity. This makes BIBO a far more stable and responsible choice for optical applications in many environments.
What's more, it has a significant software in economical generation of ultrabright entangled photons as a result of blue pumped spontaneous parametric down conversions (SPDC).
The vast majority of conventional nonlinear crystals like BBO, LBO, BiBO or KTP for frequency doubling, tripling and quadrupling of the basic laser radiation are offered from stock. Buyer-precise dimensions and AR coatings are supplied at competitive prices.

Lithium niobate (LiNbO3) and lithium tantalate (LiTaO3) are elements with a comparatively strong nonlinearity. They are often utilized for nonlinear frequency conversion in addition to for electro-optic modulators. The two materials can be found in congruent and in stoichiometric variety, with vital variances relating to periodic poling and photorefractive effects (see underneath). Lithium niobate and tantalate tend to be the most often applied materials from the context of periodic poling; the resulting components are termed PPLN (periodically poled lithium niobate) and PPLT, respectively, or PPSLN and PPSLT to the stoichiometric versions.
Operation of nonlinear crystals at temperatures beneath home temperature (to accomplish section matching) is normally problematic, as it may well produce condensation of water around the crystal surfaces if the here bordering air is just not very dry.
In the case of ultrashort pulses the substantial group velocity mismatch enforces using a shorter crystal, which demands significant optical intensities to get a presented conversion effectiveness.
Crystals that happen to be non-critically period-matched in a very crystal oven may show complications in the event the crystal temperature is changed as well rapidly or as well normally. Specifically, anti-reflection coatings may be ruined because of various thermal expansion coefficients of the concerned products.
) to blow off dust and other free contaminants initial. If a dry nitrogen line is accessible within the lab, an air gun can be utilized to blow away dust particles. Blow from the surface area gently. Will not blow from the crystal by itself from the hand!

High electrical power laser process: BIBO crystals are perfect for use in superior-ability laser methods due to their higher problems threshold as well as their capacity to withstand large-depth laser beams without the need of harm. This offers BIBO crystals a major advantage in laser programs that call for high Vitality output.
Our crystals are Utilized in an array of purposes, like different sorts of nonlinear frequency conversion and electro-optics, but additionally quantum technology.
