The susceptibility to moisture of BiBO is rather very low. Having said that, users are encouraged to supply dry disorders for equally use and storage of BiBO to extend the life time. Drinking water condensation on crystal surfaces really should be absolutely prevented Anytime.
If the crystal surfaces are still “dirty�?just after the above mentioned cleaning techniques, the surfaces might have been weakened. Please Get in touch with us for rework of the crystals.
Inspect the crystal floor for dust and stains by Keeping it in close proximity to a bright seen-gentle source. Viewing at various angles might help see scattering from dust and stains. The crystal floor has to be cleaned as described beneath if dust and stains are identified.
Normally, the crystal materials ought to have a large optical transparency for all wavelengths included �?as an example, for pump, sign and idler in an optical parametric amplifier.
Equally have a comparatively small injury threshold, but do not need to be operated at higher intensities because of their high nonlinearity. They have a tendency for photorefractive results, which are detrimental for frequency conversion, but are employed for, e.g., holographic knowledge storage in Fe-doped LiNbO3 crystals. The tendency for “photorefractive damage�?is dependent strongly on the material composition; e.g. it may be reduced by means of MgO doping and by utilizing a stoichiometric composition.
GWU-Lasertechnik has in excess of 30 decades of knowledge in distributing laser crystals. Select GWU to benefit from our large knowledge As well as in-industry knowledge!
The selection of the most fitted crystal product for any presented application is usually considerably from trivial; it need to entail the consideration of numerous areas. As an example, a high nonlinearity for frequency conversion of ultrashort pulses does not help When the conversation duration is strongly constrained by a considerable team velocity mismatch along with the reduced injury threshold limits the relevant optical intensities.
Bismuth Triborate (BiB3O6 or BIBO) is really a newly designed nonlinear optical crystal. It possesses large productive nonlinear coefficient, substantial injury threshold and inertness with respect to dampness.
Although the nonlinear coefficient of KTP crystal is big, the laser damage threshold is very low, which is able to result in issues for example refractive index transform and transmission loss. BIBO crystal has greater laser damage threshold and better second harmonic conversion performance. Though LBO and B-BBO are by far the most practical, They are really little in sizing and have specified hygroscopicity, when BIBO crystals are non-soaked and will grow to large size. These positive aspects empower BIBO crystals to get extensively employed.
Too much optical intensities in the course of operation could immediately harm a crystal. However, nonlinear crystals frequently must be operated not significantly from their optical problems threshold to realize a adequately large conversion performance. This suggests a trade-off among conversion performance and crystal lifetime.
Bismuth Triborate (BiB3O6 or BIBO) is a freshly developed nonlinear optical crystal. It possesses big successful nonlinear coefficient, significant injury threshold and inertness with regard to moisture.
GWU-Lasertechnik offers all regular nonlinear crystals like LBO, BBO and KTP having a broad assortment of specs. Beside the properly-set up resources, progressive crystals like CLBO or BiBO with exceptional Houses for e. g. deep-UV technology or large-electricity ultrashort more info pulse lasers can be found. No matter if particular person pieces for R & D uses are necessary or Price tag-economical figures in modest, medium or huge batches with in-time shipping and delivery for the production line are essential: GWU’s devoted company helps you to locate the greatest core factors to your software.
The magnitude with the efficient nonlinear coefficient depends on the nonlinear tensor factors and over the used section-matching configuration. A large nonlinearity is vital particularly In the event the achievable optical intensities are lower.
Superior Injury Threshold: BIBO crystal has a high destruction threshold, allowing for it to resist high laser electric power without having suffering destruction. This characteristic helps make BIBO suitable for use in higher-ability laser programs.
