Hygroscopic crystal components deteriorate when they're not often saved in sufficiently dry air (or a dry purge gasoline). This applies e.g. to KDP and BBO, and in a lesser extent to LBO. It could be useful to maintain this type of crystal in a relatively elevated temperature, that makes it simpler to keep it dry.
Additionally, it has a crucial application in effective generation of ultrabright entangled photons via blue pumped spontaneous parametric down conversions (SPDC).
Inspect the crystal surface for dust and stains by holding it near a bright noticeable-mild supply. Viewing at unique angles can help see scattering from dust and stains. The crystal area needs to be cleaned as explained under if dust and stains are located.
Normally, the crystal material should have a large optical transparency for all wavelengths involved �?for instance, for pump, signal and idler in an optical parametric amplifier.
Both equally have a comparatively minimal problems threshold, but don't have to be operated at significant intensities because of their higher nonlinearity. They have got an inclination for photorefractive effects, which might be harmful for frequency conversion, but are utilized for, e.g., holographic info storage in Fe-doped LiNbO3 crystals. The inclination for “photorefractive destruction�?depends strongly on the material composition; e.g. it may be diminished by means of MgO doping and by making use of a stoichiometric composition.

Bismuth Triborate (BiB3O6 or BIBO) is usually a freshly made nonlinear optical crystal. It possesses substantial successful nonlinear coefficient, substantial harm threshold and inertness with respect to moisture.
They show excellent homogeneity over large volumes and also have a high problems threshold, but are hygroscopic and have a minimal nonlinearity.
Abnormal optical intensities for the duration of Procedure may possibly promptly problems a crystal. Regrettably, nonlinear crystals frequently must be operated not considerably from their optical harm threshold to achieve a adequately large conversion effectiveness. This implies a trade-off involving conversion efficiency and crystal life span.
Bismuth Triborate (BiB3O6 or BIBO) can be read more a recently made nonlinear optical crystal. It possesses massive successful nonlinear coefficient, significant injury threshold and inertness with regard to moisture.
