The susceptibility to moisture of BiBO is very lower. Having said that, users are suggested to supply dry circumstances for equally use and storage of BiBO to prolong the lifetime. Water condensation on crystal surfaces need to be Completely avoided Anytime.
If the crystal surfaces are still “filthy�?following the above mentioned cleansing processes, the surfaces might have been weakened. Please Call us for rework from the crystals.
BiB3O6 (BIBO) is an excellent sort of nonlinear Optical Crystal. NLO Crystals BIBO Crystals possesses significant helpful nonlinear coeffcient, vast State-of-the-art attribute for that NLO software broad transparency vary from 286nm to 2500nm, large problems threshold and inertness with respect to humidity.
Crystal life span can also be strongly depending on the fabric high-quality, although selected degradation phenomena seem like intrinsic limits of the fabric.
The two have a relatively low injury threshold, but don't have to be operated at higher intensities due to their large nonlinearity. They may have a tendency for photorefractive outcomes, that are detrimental for frequency conversion, but are useful for, e.g., holographic details storage in Fe-doped LiNbO3 crystals. The inclination for “photorefractive damage�?is dependent strongly on the material composition; e.g. it may be diminished by means of MgO doping and by making use of a stoichiometric composition.

Lithium niobate (LiNbO3) and lithium tantalate (LiTaO3) are supplies with a comparatively sturdy nonlinearity. They in many cases are used for nonlinear frequency conversion in addition to for electro-optic modulators. Both of those supplies are available in congruent and in stoichiometric sort, with critical more info distinctions regarding periodic poling and photorefractive results (see below). Lithium niobate and tantalate tend to be the most frequently utilized materials while in the context of periodic poling; the resulting materials are termed PPLN (periodically poled lithium niobate) and PPLT, respectively, or PPSLN and PPSLT for your stoichiometric versions.
Scientific exploration and progress: BIBO crystals also Enjoy a significant position in scientific research and growth. Its superb nonlinear optical performance delivers new tools and choices for ultrafast phenomenon investigation, robust subject physics, biomedical imaging together with other fields
Although the nonlinear coefficient of KTP crystal is big, the laser problems threshold is very low, which is able to trigger challenges like refractive index improve and transmission loss. BIBO crystal has higher laser hurt threshold and better second harmonic conversion effectiveness. While LBO and B-BBO are essentially the most sensible, These are compact in dimensions and also have sure hygroscopicity, even though BIBO crystals are non-moist and will mature to large dimension. These pros empower BIBO crystals being widely made use of.
Crystals which happen to be non-critically phase-matched inside a crystal oven could exhibit complications when the crystal temperature is changed way too quickly or much too typically. Especially, anti-reflection coatings can be damaged because of diverse thermal expansion coefficients with the associated materials.
) to blow off dust as well as other free contaminants first. If a dry nitrogen line is out there in the lab, an air gun may also be used to blow absent dust particles. Blow off the area Carefully. Never blow from the crystal alone out of your hand!
GWU-Lasertechnik presents all typical nonlinear crystals like LBO, BBO and KTP that has a wide range of specs. Beside the nicely-proven components, revolutionary crystals like CLBO or BiBO with outstanding Homes for e. g. deep-UV technology or large-electricity ultrashort pulse lasers can be found. Regardless of if particular person pieces for R & D uses are demanded or Value-efficient figures in compact, medium or massive batches with in-time supply for the generation line are essential: GWU’s dedicated support helps you to find the most effective Main factors for your software.
Optical crystals can exhibit various kinds of optical nonlinearities, which can be used in several means:
Our crystals are Utilized in a variety of purposes, such as numerous sorts of nonlinear frequency conversion and electro-optics, but in addition quantum know-how.
