Hygroscopic crystal elements deteriorate when they're not often saved in adequately dry air (or maybe a dry purge gas). This applies e.g. to KDP and BBO, As well as in a lesser extent to LBO. It may be beneficial to keep this type of crystal at a to some degree elevated temperature, which makes it simpler to retain it dry.
Inertness to Dampness: BIBO crystal is inert to dampness, which implies it doesn't degrade or eliminate its optical Qualities when subjected to humidity. This can make BIBO a far more stable and reputable selection for optical apps in various environments.
Inspect the crystal area for dust and stains by Keeping it around a shiny seen-gentle supply. Viewing at distinct angles will help see scattering from dust and stains. The crystal surface area must be cleaned as described below if dust and stains are uncovered.
Typically, the crystal materials ought to have a large optical transparency for all wavelengths involved �?for example, for pump, signal and idler in an optical parametric amplifier.
Both have a relatively lower harm threshold, but do not need to be operated at substantial intensities due to their significant nonlinearity. They have an inclination for photorefractive outcomes, that happen to be harmful for frequency conversion, but are used get more info for, e.g., holographic information storage in Fe-doped LiNbO3 crystals. The tendency for “photorefractive hurt�?relies upon strongly on the fabric composition; e.g. it could be lowered by way of MgO doping and by utilizing a stoichiometric composition.
Regardless of whether the crystal product or coating will not be delicate to drinking water, smaller drinking water droplets may well aim laser radiation additional tightly than less than usual operation, and so problems the crystal substance.
The selection in the best suited crystal product for any given software is commonly far from trivial; it ought to entail the thought of numerous features. For instance, a high nonlinearity for frequency conversion of ultrashort pulses doesn't support Should the interaction length is strongly constrained by a considerable group velocity mismatch and also the minimal injury threshold boundaries the applicable optical intensities.
Procedure of nonlinear crystals at temperatures below place temperature (to achieve period matching) is generally problematic, as it may lead to condensation of water about the crystal surfaces In case the surrounding air isn't pretty dry.
In the situation of ultrashort pulses the substantial team velocity mismatch enforces using a shorter crystal, which demands large optical intensities for just a provided conversion performance.
Borates like LBO and BBO also work well in broadly tunable optical parametric oscillators and optical parametric chirped-pulse amplification.
Bismuth Triborate (BiB3O6 or BIBO) is really a newly designed nonlinear optical crystal. It possesses substantial effective nonlinear coefficient, substantial damage threshold and inertness with respect to dampness.

Higher electric power laser method: BIBO crystals are perfect for use in large-power laser programs due to their significant damage threshold and their skill to withstand large-depth laser beams without problems. This gives BIBO crystals an important advantage in laser programs that demand large Strength output.
Our crystals are Utilized in an array of programs, which includes various kinds of nonlinear frequency conversion and electro-optics, but will also quantum technological know-how.
