Hygroscopic crystal materials deteriorate when they're not generally saved in sufficiently dry air (or perhaps a dry purge fuel). This applies e.g. to KDP and BBO, and in a lesser extent to LBO. It might be useful to keep this kind of crystal at a to some degree elevated temperature, that makes it easier to retain it dry.
Additionally, it has a significant software in effective technology of ultrabright entangled photons by way of blue pumped spontaneous parametric down conversions (SPDC).

Crystal lifetime can be strongly dependent on the material good quality, While selected degradation phenomena look like intrinsic limits of the fabric.
BIBO crystals can be used as superior-efficiency frequency doubling and frequency summing devices and have broad application prospective customers in optical parametric oscillation (OPO).
Dust and stains on crystal surfaces can result in scattering/decline of sunshine and may even respond with gentle to wreck optical surfaces in a significant incident laser ability.
Lithium niobate (LiNbO3) and lithium tantalate (LiTaO3) are materials with a relatively powerful nonlinearity. They are frequently used for nonlinear frequency conversion and likewise for electro-optic modulators. Both of those supplies can be found in congruent As well as in stoichiometric variety, with essential dissimilarities regarding periodic poling and photorefractive results (see below). Lithium niobate and tantalate are classified as the most often employed products inside the context of periodic poling; the ensuing elements are identified as PPLN (periodically poled lithium niobate) and PPLT, respectively, or PPSLN and PPSLT with the stoichiometric versions.
Scientific research and improvement: BIBO crystals also Enjoy an essential role in scientific investigate and progress. Its great nonlinear optical general performance provides new equipment and prospects for ultrafast phenomenon research, solid subject physics, biomedical imaging along with other fields
They exhibit good more info homogeneity over huge volumes and have a higher harm threshold, but are hygroscopic and also have a lower nonlinearity.
Many various Homes of the nonlinear crystal can be critical for an software e.g. in nonlinear frequency conversion:
) to blow off dust together with other unfastened contaminants to start with. If a dry nitrogen line is available within the lab, an air gun may also be employed to blow away dust particles. Blow from the area Carefully. Usually do not blow off the crystal by itself from your hand!
GWU-Lasertechnik provides all common nonlinear crystals like LBO, BBO and KTP using a wide variety of specifications. Beside the nicely-proven supplies, ground breaking crystals like CLBO or BiBO with outstanding Attributes for e. g. deep-UV generation or superior-power ultrashort pulse lasers are available. Irrespective of if personal pieces for R & D needs are required or Price-productive figures in smaller, medium or big batches with in-time supply for your output line are essential: GWU’s dedicated assistance helps to locate the greatest core elements for your personal application.
linear absorption, which often can lead to heating at large optical electric power amounts, so the period matching is disturbed, and thermal lensing may well manifest
flux-developed KTP and RTP with its significant nonlinearity, also in variants with higher grey tracking resistance
