Hygroscopic crystal components deteriorate when they're not constantly stored in adequately dry air (or even a dry purge fuel). This applies e.g. to KDP and BBO, and in a lesser extent to LBO. It could be valuable to help keep this kind of crystal at a to some degree elevated temperature, which makes it simpler to retain it dry.
Kingwin Optics gives higher-excellent BIBO crystal with Innovative coatings and mounting options, which makes it a fantastic choice for researchers, engineers, and suppliers trying to get productive and responsible nonlinear optical parts.

The amount of the solvent could be adjusted for numerous crystal dimension so the lens tissue is stored damp for the whole drag but there is not any visible trace of solvent within the crystal area after the drag is concluded. Inspect the floor and repeat if needed, but only use Every single sheet of lens tissue when.
BIBO crystals can be used as large-effectiveness frequency doubling and frequency summing equipment and also have broad application prospective clients in optical parametric oscillation (OPO).
Employing our advertising and marketing offer, you can Show your logo, additional underneath your products description, and these will read more been seen by many photonics professionals.
Lithium niobate (LiNbO3) and lithium tantalate (LiTaO3) are resources with a relatively potent nonlinearity. They are often useful for nonlinear frequency conversion and in addition for electro-optic modulators. Both elements can be found in congruent and in stoichiometric kind, with significant variations relating to periodic poling and photorefractive outcomes (see down below). Lithium niobate and tantalate will be the most frequently applied resources in the context of periodic poling; the ensuing components are referred to as PPLN (periodically poled lithium niobate) and PPLT, respectively, or PPSLN and PPSLT to the stoichiometric versions.
Procedure of nonlinear crystals at temperatures below space temperature (to achieve phase matching) is generally problematic, as it might result in condensation of water around the crystal surfaces if the bordering air is not really extremely dry.
They exhibit very good homogeneity about huge volumes and possess a higher hurt threshold, but are hygroscopic and have a lower nonlinearity.
Crystals which might be non-critically period-matched inside a crystal oven may perhaps show difficulties when the crystal temperature is modified as well speedily or far too usually. In particular, anti-reflection coatings might be weakened resulting from various thermal expansion coefficients from the involved resources.
Non-linear Optical (NLO) crystals supply an enormously versatile Alternative for generating new wavelengths from existing, off-the-shelf laser sources. The optical wavelength spectrum is utilized by a considerable and continually expanding number of programs, from manufacturing of health care lasers, quantum networking & computing by way of to environmental sensing together with quite a few Many others.
