Hygroscopic crystal components deteriorate when they're not normally kept in adequately dry air (or possibly a dry purge fuel). This is applicable e.g. to KDP and BBO, and in a lesser extent to LBO. It can be beneficial to help keep this kind of crystal at a rather elevated temperature, that makes it easier to keep it dry.
In addition it has an important software in productive technology of ultrabright entangled photons via blue pumped spontaneous parametric down conversions (SPDC).
BiB3O6 (BIBO) is a superb kind of nonlinear Optical Crystal. NLO Crystals BIBO Crystals possesses substantial effective nonlinear coeffcient, wide Superior characteristic with the NLO application broad transparency range between 286nm to 2500nm, high injury threshold and inertness with respect to moisture.
With a significant helpful nonlinear coefficient, substantial problems threshold, and inertness to dampness, BIBO crystal presents various pros more than other nonlinear optical supplies like LBO and BBO.

Lithium niobate here (LiNbO3) and lithium tantalate (LiTaO3) are materials with a comparatively sturdy nonlinearity. They are frequently used for nonlinear frequency conversion in addition to for electro-optic modulators. Equally supplies can be found in congruent and in stoichiometric kind, with critical variations about periodic poling and photorefractive consequences (see under). Lithium niobate and tantalate will be the most often applied supplies during the context of periodic poling; the resulting elements are known as PPLN (periodically poled lithium niobate) and PPLT, respectively, or PPSLN and PPSLT for that stoichiometric variations.
Bismuth Triborate (BiB3O6 or BIBO) is often a recently created nonlinear optical crystal. It possesses big efficient nonlinear coefficient, high destruction threshold and inertness with regard to moisture.
In the situation of ultrashort pulses the superior team velocity mismatch enforces the usage of a shorter crystal, which needs large optical intensities to get a given conversion effectiveness.
Borates such as LBO and BBO also get the job done well in broadly tunable optical parametric oscillators and optical parametric chirped-pulse amplification.
) to blow off dust and various free contaminants very first. If a dry nitrogen line is obtainable inside the lab, an air gun may also be used to blow absent dust particles. Blow off the floor gently. Never blow off the crystal alone out of your hand!

Higher electrical power laser program: BIBO crystals are ideal for use in significant-electric power laser devices due to their high destruction threshold and their ability to face up to large-depth laser beams with no damage. This provides BIBO crystals a substantial edge in laser applications that call for higher Electricity output.
flux-grown KTP and RTP with its higher nonlinearity, also in variants with large gray tracking resistance
