BIBO crystal (bismuth triborate) is a comparatively novel nonlinear content when put next with BBO and LBO crystals. BIBO crystal surpasses BBO with regard to its successful nonlinearity, though also providing a broader bandgap in comparison to KTP crystal.
If the crystal surfaces are still “filthy�?after the above mentioned cleaning processes, the surfaces may need been harmed. Please Speak to us for rework from the crystals.
Inspect the crystal floor for dust and stains by Keeping it in close proximity to a bright seen-mild supply. Viewing at diverse angles may also help see scattering from dust and stains. The crystal surface area needs to be cleaned as described beneath if dust and stains are observed.
With a big helpful nonlinear coefficient, significant damage threshold, and inertness to humidity, BIBO crystal offers a number of advantages around other nonlinear optical supplies such as LBO and BBO.
Each have a comparatively minimal damage threshold, but do not must be operated at superior intensities due to their substantial nonlinearity. They have got a tendency for photorefractive results, that are detrimental for frequency conversion, but are useful for, e.g., holographic information storage in Fe-doped LiNbO3 crystals. The tendency for “photorefractive problems�?relies upon strongly on the material composition; e.g. it could be diminished by using MgO doping and by utilizing a stoichiometric composition.
Regardless of whether the crystal materials or coating is not sensitive to h2o, modest drinking water droplets might emphasis laser radiation additional tightly than under typical Procedure, and thus problems the crystal content.
Filters down below or the get more info form at The underside may be used to aid merchandise search or make more inquiries.
Procedure of nonlinear crystals at temperatures under space temperature (to attain phase matching) is generally problematic, as it may well bring on condensation of drinking water within the crystal surfaces In the event the surrounding air is not pretty dry.
In the case of ultrashort pulses the higher group velocity mismatch enforces the use of a shorter crystal, which calls for significant optical intensities for just a offered conversion performance.
Borates for instance LBO and BBO also perform well in broadly tunable optical parametric oscillators and optical parametric chirped-pulse amplification.
Non-linear Optical (NLO) crystals present an enormously versatile Answer for generating new wavelengths from current, off-the-shelf laser resources. The optical wavelength spectrum is utilized by a sizable and frequently increasing number of apps, from production of medical lasers, quantum networking & computing by to environmental sensing in addition to quite a few Many others.
GWU-Lasertechnik presents all typical nonlinear crystals like LBO, BBO and KTP that has a wide variety of requirements. Beside the effectively-recognized products, impressive crystals like CLBO or BiBO with outstanding Qualities for e. g. deep-UV era or superior-ability ultrashort pulse lasers can be found. Irrespective of if unique parts for R & D needs are expected or Price tag-economical quantities in compact, medium or significant batches with in-time supply with the output line are desired: GWU’s focused assistance helps you to discover the greatest core components for your personal software.
Optical crystals can show diverse forms of optical nonlinearities, which may be utilized in various strategies:
Our crystals are Employed in a wide array of apps, like several varieties of nonlinear frequency conversion and electro-optics, and also quantum technological know-how.
