The TSSG process is a relatively new technique which has attained popularity for its ability to create high-quality crystals with reduced defect density.
Lithium niobate (LiNbO3) and lithium tantalate (LiTaO3) are materials with a relatively strong nonlinearity. They will often be utilized for nonlinear frequency conversion as well as for electro-optic modulators. Both of those supplies are available in congruent and in stoichiometric variety, with important distinctions regarding periodic poling and photorefractive consequences (see beneath). Lithium niobate and tantalate would be the most often utilised components during the context of periodic poling; the resulting supplies are known as PPLN (periodically poled lithium niobate) and PPLT, respectively, or PPSLN and PPSLT to the stoichiometric versions.
These qualities limit the alignment sensitivity of your optical system and be certain better beam propagation. The fewer stringent alignment needs and far better beam high quality conferred by these capabilities normally idea the size in favor of LBO Crystals above other nonlinear optical crystals.
retains a considerable stock of LBO crystals which can be shipped inside one 7 days upon receipt of the acquisition buy. (
The flux method is an additional prevalent technique that entails dissolving the beginning products within a flux and gradually cooling the answer to form crystals.
A standard strategy for obtaining ultrathin crystals would be to initially optically Get hold of a thicker nonlinear crystal with some substrate (e.g. of fused silica) after which to shine the crystal right down to the needed thickness of e.
X-ray diffraction is a robust technique for analyzing the crystal LBO Crystal framework and orientation of LBO nonlinear crystals.
The Czochralski technique allows for the production of large solitary crystals with superb high quality, though the flux technique can decrease impurities and defects during the crystal. The TSSG method supplies precise Handle around crystal orientation and defect density, along with the hybrid method combines the benefits of the TSSG and Czochralski methods.
Working with our promoting deal, you are able to Screen your brand, further beneath your merchandise description, and these will been seen by several photonics pros.
Among the most popular applications of LBO nonlinear crystals is frequency doubling, exactly where the fundamental frequency of a laser beam is doubled to provide a greater frequency output.
If you do not find the acceptable goods higher than, chances are you'll let us know your necessities or applications in the form down below. Our income or technical workers can get back to you as soon as possible.
Within the more time wavelength region of the spectrum, LBO is useful for tunable OPO’s to produce near-infrared radiation.
Optical crystals can exhibit diverse types of optical nonlinearities, that may be used in different means:
They show good homogeneity more than huge volumes and also have a substantial problems threshold, but are hygroscopic and also have a very low nonlinearity.
