The susceptibility to moisture of BiBO is extremely low. However, buyers are recommended to provide dry conditions for both of those use and storage of BiBO to extend the lifetime. Drinking water condensation on crystal surfaces should be Certainly averted Anytime.
Inertness to Moisture: BIBO crystal is inert to moisture, which suggests it doesn't degrade or shed its optical Attributes when subjected to humidity. This will make BIBO a far more steady and dependable option for optical programs in several environments.
five mm to minimize team velocity mismatch and are ideal for frequency doubling or tripling of Ti:sapphire and Yb:doped laser pulses. The critical and noncritical stage matching LBO crystals are perfect for second or 3rd harmonic technology of Nd:YAG and Yb:doped lasers.
Typically, the crystal product should have a high optical transparency for all wavelengths concerned �?such as, for pump, signal and idler within an optical parametric amplifier.
BIBO crystals can be employed as large-effectiveness frequency doubling and frequency summing products and possess wide software prospective customers in optical parametric oscillation (OPO).
GWU-Lasertechnik has in excess of 30 years of expertise in distributing laser crystals. Choose GWU to benefit from our extensive understanding As well as in-field practical experience!
Lithium niobate (LiNbO3) and lithium tantalate (LiTaO3) are supplies with a comparatively potent nonlinearity. They will often be useful for nonlinear frequency conversion in addition to for electro-optic modulators. Both equally resources are available in congruent As well as in stoichiometric form, with essential dissimilarities regarding periodic poling and photorefractive consequences (see under). Lithium niobate and tantalate would be the most frequently used resources from the context of periodic poling; the resulting elements are known as PPLN (periodically poled lithium niobate) and PPLT, respectively, or PPSLN and PPSLT for your stoichiometric versions.
Crylink is surely an open System, equally as our mission is to attach price, Crylink thinks that every particular person and each company has distinctive price, and we hope to attach with useful you to provide value and replicate value jointly.
Although the nonlinear coefficient of KTP crystal is large, the laser injury threshold is lower, which will bring about difficulties BIBO Crystal which include refractive index modify and transmission decline. BIBO crystal has higher laser damage threshold and higher next harmonic conversion efficiency. Even though LBO and B-BBO are one of the most functional, These are smaller in dimensions and also have specified hygroscopicity, although BIBO crystals are non-moist and will grow to big measurement. These rewards empower BIBO crystals to generally be extensively utilised.
Extreme optical intensities throughout operation may well quickly harm a crystal. Regretably, nonlinear crystals typically must be operated not much from their optical destruction threshold to realize a adequately large conversion performance. This implies a trade-off amongst conversion performance and crystal lifetime.
Non-linear Optical (NLO) crystals provide an enormously versatile Option for generating new wavelengths from present, off-the-shelf laser sources. The optical wavelength spectrum is utilized by a sizable and constantly expanding assortment of apps, from production of health-related lasers, quantum networking & computing by to environmental sensing and many others.
This combination tends to make BIBO crystal exceptionally suited for harnessing the phenomenon of 2nd harmonic era (SHG) inside solid-state lasers and laser diodes.
linear absorption, that may cause heating at significant optical energy amounts, so the period matching is disturbed, and thermal lensing may well manifest
Large Hurt Threshold: BIBO crystal has a high injury threshold, permitting it to withstand high laser energy with out struggling hurt. This attribute makes BIBO appropriate for use in significant-ability laser units.
