Inertness to Moisture: BIBO crystal is inert to moisture, meaning it does not degrade or eliminate its optical Houses when subjected to humidity. This will make BIBO a far more secure and responsible option for optical apps in different environments.
It also has a very important application in productive era of ultrabright entangled photons by way of blue pumped spontaneous parametric down conversions (SPDC).

Usually, the crystal product ought to have a large optical transparency for all wavelengths concerned �?for example, for pump, signal and idler within an optical parametric amplifier.
Each have a relatively reduced damage threshold, but never must be operated at substantial intensities due to their higher nonlinearity. They have an inclination for photorefractive outcomes, which can be harmful for frequency conversion, but are useful for, e.g., holographic facts storage in Fe-doped LiNbO3 crystals. The tendency for “photorefractive injury�?relies upon strongly on the fabric composition; e.g. it may be decreased via MgO doping and through the use of a stoichiometric composition.
Making use of our promotion package, you'll be able to Screen your logo, further more beneath your solution description, and these will been witnessed by quite a few photonics industry experts.
Filters underneath or the form at The underside may be used to help product look for or make additional inquiries.
Crylink is an open platform, just as our mission is to connect worth, Crylink believes that every man or woman and every firm has one of a kind price, and we hope to connect with worthwhile you to deliver value and replicate benefit together.
Although the nonlinear coefficient of KTP crystal is significant, the laser injury threshold is small, that can cause troubles such as refractive index adjust and transmission reduction. BIBO crystal has bigger laser harm threshold and higher 2nd harmonic conversion performance. Although LBO and B-BBO are one of the most simple, They're tiny in measurement and also have sure hygroscopicity, though BIBO crystals are non-soaked and will mature to large size. These advantages help BIBO crystals to generally be commonly applied.
Extreme optical intensities in the course of Procedure may possibly instantaneously damage a crystal. Sadly, nonlinear crystals usually have to be operated not considerably from their optical hurt threshold to achieve a sufficiently superior conversion efficiency. This means a trade-off concerning conversion efficiency and crystal life time.
Bismuth Triborate (BiB3O6 or BIBO) is actually a freshly created nonlinear optical crystal. It possesses huge helpful nonlinear coefficient, large problems threshold and inertness with regard to humidity.
GWU-Lasertechnik gives all standard nonlinear crystals like LBO, BBO and KTP by using a wide selection of technical specs. Beside the perfectly-set up elements, revolutionary more info crystals like CLBO or BiBO with fantastic Attributes for e. g. deep-UV technology or higher-electricity ultrashort pulse lasers can be obtained. No matter if person pieces for R & D reasons are essential or Value-successful figures in modest, medium or substantial batches with in-time delivery for that generation line are wanted: GWU’s committed provider helps to find the ideal core components for your personal software.
linear absorption, that may cause heating at superior optical electricity levels, so which the period matching is disturbed, and thermal lensing may well take place
Significant Problems Threshold: BIBO crystal contains a significant problems threshold, letting it to resist higher laser energy without struggling injury. This characteristic would make BIBO appropriate for use in superior-energy laser units.
