The susceptibility to dampness of BiBO is quite minimal. Nonetheless, customers are advised to offer dry situations for each use and storage of BiBO to lengthen the life time. Water condensation on crystal surfaces really should be Completely prevented at any time.
Inertness to Dampness: BIBO crystal is inert to humidity, which suggests it does not degrade or lose its optical Attributes when exposed to humidity. This tends to make BIBO a far more steady and reliable selection for optical applications in various environments.
5 mm to attenuate group velocity mismatch and are perfect for frequency doubling or tripling of Ti:sapphire and Yb:doped laser pulses. The important and noncritical stage matching LBO crystals are perfect for second or 3rd harmonic era of Nd:YAG and Yb:doped lasers.

BIBO crystals can be utilized as substantial-performance frequency doubling and frequency summing equipment and also have broad software prospective customers in optical parametric oscillation (OPO).
Dust and stains on crystal surfaces could cause scattering/decline of sunshine and can even react with gentle to damage optical surfaces in a substantial incident laser electricity.
Lithium niobate (LiNbO3) and lithium tantalate (LiTaO3) are components with a comparatively sturdy nonlinearity. They in many cases are employed for nonlinear frequency conversion and likewise for electro-optic modulators. Both equally elements are available in congruent and in stoichiometric variety, with significant discrepancies regarding periodic poling and photorefractive effects (see under). Lithium niobate and tantalate will be the most frequently utilised products while in the context of periodic poling; the resulting materials are named PPLN (periodically poled lithium niobate) and PPLT, respectively, or PPSLN and PPSLT for the stoichiometric versions.
And is particularly useful for creating wavelengths inside the eco-friendly and blue spectrum by way of ongoing-wave (CW) radiation. The elevated powerful nonlinearity of BIBO crystal not just boosts the efficiency on the SHG procedure but will also facilitates the utilization of shorter crystal lengths—an indispensable attribute when endeavoring to website engineer compact laser techniques.
Although the nonlinear coefficient of KTP crystal is substantial, the laser harm threshold is very low, that will trigger complications such as refractive index transform and transmission loss. BIBO crystal has increased laser damage threshold and higher next harmonic conversion efficiency. Though LBO and B-BBO are probably the most functional, they are tiny in dimensions and possess certain hygroscopicity, while BIBO crystals are non-damp and can expand to large dimension. These benefits empower BIBO crystals to be widely used.
Borates for example LBO and BBO also function very well in broadly tunable optical parametric oscillators and optical parametric chirped-pulse amplification.
) to blow off dust along with other free contaminants 1st. If a dry nitrogen line is on the market from the lab, an air gun can even be applied to blow away dust particles. Blow off the area gently. Don't blow from the crystal by itself out of your hand!
China BIBO crystals can be used don't just as superior-performance frequency doubling and frequency summing products, but also have broad software prospective buyers in the sphere of optical parametric oscillation (OPO), and What's more, it has a vital application from the effective technology of ultrabright entangled photons through blue pumped Spontaneous Parametric Down Conversions (Also Know as SPDC).
Optical crystals can exhibit diverse varieties of optical nonlinearities, that may be utilized in a variety of approaches:
High Damage Threshold: BIBO crystal contains a high injury threshold, letting it to resist large laser electrical power without having struggling problems. This characteristic makes BIBO well suited for use in substantial-electricity laser techniques.
