Hygroscopic crystal materials deteriorate when they're not normally saved in adequately dry air (or a dry purge fuel). This is applicable e.g. to KDP and BBO, and in a lesser extent to LBO. It can be useful to keep this kind of crystal in a rather elevated temperature, which makes it easier to continue to keep it dry.
What's more, it has a very important software in economical generation of ultrabright entangled photons by means of blue pumped spontaneous parametric down conversions (SPDC).
Inspect the crystal surface area for dust and stains by holding it close to a dazzling noticeable-gentle resource. Viewing at unique angles may help see scattering from dust and stains. The crystal surface must be cleaned as described down below if dust and stains are located.
Crystal life time can be strongly dependent on the material top quality, Though certain degradation phenomena appear to be intrinsic limitations of the material.
The two have a relatively very low injury threshold, but will not should be operated at higher intensities because of their high nonlinearity. They have a tendency for photorefractive effects, which can be detrimental for frequency conversion, but are useful for, e.g., holographic facts storage in Fe-doped LiNbO3 crystals. The tendency for “photorefractive injury�?is dependent strongly on the material composition; e.g. it might be reduced by means of MgO doping and through the use of a stoichiometric composition.
GWU-Lasertechnik has a lot more than thirty many years of encounter in distributing laser crystals. Opt for GWU to gain from our broad knowledge and in-subject encounter!
Filters beneath or the shape at the bottom can be utilized to help products search or make further inquiries.
Bismuth Triborate (BiB3O6 or BIBO) is really a newly designed nonlinear optical crystal. It possesses substantial helpful nonlinear coefficient, higher injury threshold and inertness with respect to dampness.
Although the nonlinear coefficient of KTP crystal is huge, the laser hurt threshold is very low, which is able to cause issues like refractive index modify and transmission reduction. BIBO crystal has larger laser harm threshold and higher next harmonic conversion effectiveness. Though LBO and B-BBO are essentially the most sensible, They're smaller in measurement and have sure hygroscopicity, though BIBO crystals are non-damp and can mature to substantial measurement. These benefits help BIBO crystals being widely utilised.
Too much optical intensities in the course of operation could instantly damage a crystal. Sadly, nonlinear crystals typically should be operated not considerably from their optical destruction threshold to accomplish a sufficiently large conversion effectiveness. This means a trade-off amongst conversion effectiveness and crystal lifetime.
Non-linear Optical (NLO) crystals give an enormously versatile Option for generating new wavelengths from existing, off-the-shelf laser sources. The optical wavelength spectrum is used by a substantial and continuously expanding selection of apps, from manufacturing of clinical lasers, quantum networking & computing by means of to environmental sensing along with lots of Other individuals.
GWU-Lasertechnik provides all normal nonlinear crystals like LBO, BBO more info and KTP which has a wide assortment of specs. Beside the nicely-established resources, revolutionary crystals like CLBO or BiBO with outstanding Attributes for e. g. deep-UV era or high-electricity ultrashort pulse lasers can be obtained. Irrespective of if person parts for R & D reasons are required or Expense-economical numbers in smaller, medium or big batches with in-time shipping for the generation line are wanted: GWU’s dedicated services helps you to locate the most effective core components to your application.
The magnitude of the productive nonlinear coefficient depends upon the nonlinear tensor factors and about the utilized period-matching configuration. A higher nonlinearity is important especially Should the achievable optical intensities are lower.
Our crystals are used in a wide range of purposes, together with several forms of nonlinear frequency conversion and electro-optics, but in addition quantum technological innovation.
