Hygroscopic crystal materials deteriorate when they are not constantly stored in adequately dry air (or even a dry purge fuel). This is applicable e.g. to KDP and BBO, As well as in a lesser extent to LBO. It may be valuable to help keep this type of crystal at a somewhat elevated temperature, which makes it much easier to continue to keep it dry.
If the crystal surfaces remain “filthy�?right after the above mentioned cleansing strategies, the surfaces may need been destroyed. Be sure to Make contact with us for rework on the crystals.
Inspect the crystal surface for dust and stains by Keeping it in the vicinity of a shiny seen-gentle supply. Viewing at diverse angles may also help see scattering from dust and stains. The crystal floor should be cleaned as described below if dust and stains are discovered.
Normally, the crystal substance should have a superior optical transparency for all wavelengths included �?such as, for pump, signal and idler in an optical parametric amplifier.
Also, it can be remarkably appealing to use a crystal content which can be critically stage-matched at home temperature because noncritical phase matching generally entails the operation with the crystal inside a temperature-stabilized crystal oven. On the other hand, the feasibility of crucial stage matching may very well be offered only for sufficiently high peak powers.

Lithium niobate (LiNbO3) and lithium tantalate (LiTaO3) are products with a relatively sturdy nonlinearity. They will often be employed for nonlinear frequency conversion and in addition for electro-optic modulators. Both elements are available in congruent As well as in stoichiometric form, with essential discrepancies about periodic poling and photorefractive outcomes (see under). Lithium niobate and tantalate tend to be the most frequently used materials in the context of periodic poling; the resulting materials are identified as PPLN (periodically poled lithium niobate) and PPLT, respectively, or PPSLN and PPSLT for the read more stoichiometric versions.
Scientific study and improvement: BIBO crystals also Perform an essential function in scientific research and development. Its fantastic nonlinear optical general performance provides new tools and alternatives for ultrafast phenomenon investigation, robust field physics, biomedical imaging and also other fields
Even though the nonlinear coefficient of KTP crystal is huge, the laser harm threshold is small, that can trigger complications including refractive index change and transmission reduction. BIBO crystal has better laser harm threshold and better 2nd harmonic conversion performance. Whilst LBO and B-BBO are by far the most practical, They may be smaller in dimensions and possess certain hygroscopicity, whilst BIBO crystals are non-moist and may increase to substantial sizing. These advantages enable BIBO crystals to generally be widely used.
the chemical longevity; e.g., some crystal supplies are hygroscopic, Some others undergo chemical modifications when heated in a very vacuum chamber for software of the dielectric coating
Bismuth Triborate (BiB3O6 or BIBO) is really a recently developed nonlinear optical crystal. It possesses substantial efficient nonlinear coefficient, significant hurt threshold and inertness with regard to moisture.
GWU-Lasertechnik delivers all regular nonlinear crystals like LBO, BBO and KTP that has a wide variety of specs. Beside the well-proven supplies, progressive crystals like CLBO or BiBO with exceptional Homes for e. g. deep-UV technology or substantial-power ultrashort pulse lasers are available. No matter if unique items for R & D needs are expected or Expense-productive numbers in little, medium or big batches with in-time delivery with the output line are wanted: GWU’s devoted services really helps to discover the greatest core components for your software.
Large electrical power laser program: BIBO crystals are ideal for use in high-power laser units because of their high damage threshold as well as their capacity to withstand superior-intensity laser beams with out destruction. This offers BIBO crystals a big advantage in laser apps that need significant Vitality output.
Superior Destruction Threshold: BIBO crystal has a high damage threshold, allowing it to face up to significant laser electric power devoid of suffering damage. This attribute can make BIBO appropriate for use in higher-ability laser programs.
