If you do not locate the ideal items above, you may allow us to know your prerequisites or apps in the shape below. Our product sales or complex staff members can get back again for you without delay.
What's more, it has a very important software in productive technology of ultrabright entangled photons by blue pumped spontaneous parametric down conversions (SPDC).

Typically, the crystal content must have a substantial optical transparency for all wavelengths included �?by way of example, for pump, sign and idler in an optical parametric amplifier.
BIBO crystals can be used as substantial-efficiency frequency doubling and frequency summing units and possess broad application prospective buyers in optical parametric oscillation (OPO).
Working with our advertising and marketing deal, you may Show your brand, further more underneath your products description, and these will been noticed by a lot of photonics specialists.
Lithium niobate (LiNbO3) and lithium tantalate (LiTaO3) are materials with a comparatively robust nonlinearity. They are sometimes useful for nonlinear frequency conversion and in addition for electro-optic modulators. Both materials can be found in congruent and in stoichiometric form, with crucial distinctions concerning periodic poling and photorefractive outcomes (see beneath). Lithium website niobate and tantalate will be the most frequently utilised materials during the context of periodic poling; the ensuing products are called PPLN (periodically poled lithium niobate) and PPLT, respectively, or PPSLN and PPSLT with the stoichiometric variations.
And is especially beneficial for producing wavelengths within the inexperienced and blue spectrum by constant-wave (CW) radiation. The elevated effective nonlinearity of BIBO crystal not simply enhances the efficiency on the SHG process but in addition facilitates the utilization of shorter crystal lengths—an indispensable attribute when endeavoring to engineer compact laser systems.
In the case of ultrashort pulses the high group velocity mismatch enforces the use of a shorter crystal, which demands higher optical intensities for any provided conversion effectiveness.
Borates for example LBO and BBO also perform nicely in broadly tunable optical parametric oscillators and optical parametric chirped-pulse amplification.
Bismuth Triborate (BiB3O6 or BIBO) is often a newly developed nonlinear optical crystal. It possesses huge productive nonlinear coefficient, high problems threshold and inertness with regard to dampness.
This mixture will make BIBO crystal exceptionally suited to harnessing the phenomenon of next harmonic era (SHG) within just good-point out lasers and laser diodes.
The magnitude of the successful nonlinear coefficient depends on the nonlinear tensor factors and to the used stage-matching configuration. A higher nonlinearity is vital notably When the achievable optical intensities are low.
Our crystals are Employed in a wide array of apps, like different varieties of nonlinear frequency conversion and electro-optics, but additionally quantum technological know-how.
