Inertness to Humidity: BIBO crystal is inert to moisture, which means it doesn't degrade or drop its optical Qualities when exposed to humidity. This can make BIBO a more steady and reliable selection for optical purposes in different environments.
What's more, it has a crucial application in successful era of ultrabright entangled photons by way of blue pumped spontaneous parametric down conversions (SPDC).

Commonly, the crystal product should have a significant optical transparency for all wavelengths concerned �?one example is, for pump, signal and idler within an optical parametric amplifier.
Both have a comparatively lower destruction threshold, but tend not to have to be operated at substantial intensities due to their large nonlinearity. They may have an inclination for photorefractive consequences, which happen to be detrimental for frequency conversion, but are used for, e.g., holographic information storage in Fe-doped LiNbO3 crystals. The inclination for “photorefractive harm�?is dependent strongly on the material composition; e.g. it could be lessened by way of MgO doping and by utilizing a stoichiometric composition.
GWU-Lasertechnik has more than thirty a long time of working experience in distributing laser crystals. Select GWU to take pleasure in our large information As well as in-field expertise!
The choice of your most fitted crystal product for the provided application is frequently far from trivial; it should really require the consideration of numerous elements. Such as, a significant nonlinearity for frequency conversion of ultrashort pulses doesn't assist if the conversation length is strongly limited by a large group velocity mismatch and also the lower destruction threshold restrictions the relevant optical intensities.
And is especially beneficial for building wavelengths inside the inexperienced and blue spectrum through continual-wave (CW) radiation. The elevated productive nonlinearity of BIBO crystal not just boosts the performance of your SHG method and also facilitates the utilization of shorter crystal lengths—an indispensable attribute when endeavoring to engineer compact laser techniques.
In the situation of ultrashort pulses the high group velocity mismatch enforces using a shorter crystal, which needs significant optical intensities for the supplied conversion effectiveness.
Borates like LBO and BBO also operate very well in broadly tunable optical parametric oscillators and optical parametric chirped-pulse amplification.
Bismuth Triborate (BiB3O6 or BIBO) is a freshly made nonlinear optical crystal. It possesses massive powerful nonlinear coefficient, large harm threshold and inertness with respect to humidity.
This mixture tends to make BIBO crystal exceptionally read more suited to harnessing the phenomenon of second harmonic technology (SHG) within just good-point out lasers and laser diodes.
linear absorption, which can lead to heating at large optical ability concentrations, so that the section matching is disturbed, and thermal lensing might take place
Our crystals are Employed in a wide range of applications, together with several varieties of nonlinear frequency conversion and electro-optics, but also quantum technology.
