BIBO crystal (bismuth triborate) is a relatively novel nonlinear content compared with BBO and LBO crystals. BIBO crystal surpasses BBO regarding its productive nonlinearity, though also featuring a broader bandgap compared to KTP crystal.
If the crystal surfaces are still “dirty�?soon after the above cleansing procedures, the surfaces might have been damaged. You should Get in touch with us for rework in the crystals.

Crystal life span can also be strongly dependent on the material quality, Though specified degradation phenomena appear to be intrinsic limitations of the material.
Equally have a comparatively minimal damage threshold, but tend not to need to be operated at superior intensities due to their high nonlinearity. They've a tendency for photorefractive consequences, which can be detrimental for frequency conversion, but are useful for, e.g., holographic facts storage in Fe-doped LiNbO3 crystals. The tendency for “photorefractive damage�?depends strongly on the material composition; e.g. it might be lowered by using MgO doping and through the use of a stoichiometric composition.
GWU-Lasertechnik has over thirty many years of experience in distributing laser crystals. Decide on GWU to reap the benefits of our large knowledge As well as in-subject encounter!
The selection of your most suitable crystal substance to get a supplied software is often much from trivial; it should really website include the thought of numerous elements. As an example, a significant nonlinearity for frequency conversion of ultrashort pulses does not aid When the interaction duration is strongly confined by a significant team velocity mismatch plus the very low problems threshold restrictions the relevant optical intensities.
And is especially beneficial for building wavelengths during the eco-friendly and blue spectrum through constant-wave (CW) radiation. The elevated helpful nonlinearity of BIBO crystal not merely improves the effectiveness of your SHG method but will also facilitates the utilization of shorter crystal lengths—an indispensable attribute when endeavoring to engineer compact laser techniques.
They exhibit good homogeneity around huge volumes and possess a large damage threshold, but are hygroscopic and also have a small nonlinearity.
Crystals which might be non-critically period-matched in a very crystal oven may show troubles once the crystal temperature is altered too rapidly or much too typically. Specifically, anti-reflection coatings could be damaged due to unique thermal expansion coefficients of your concerned materials.
Non-linear Optical (NLO) crystals give an enormously adaptable Alternative for generating new wavelengths from existing, off-the-shelf laser sources. The optical wavelength spectrum is utilized by a sizable and constantly increasing assortment of apps, from production of health care lasers, quantum networking & computing by to environmental sensing together with quite a few Some others.
This mix would make BIBO crystal exceptionally fitted to harnessing the phenomenon of next harmonic technology (SHG) within good-condition lasers and laser diodes.
linear absorption, which might bring about heating at substantial optical energy degrees, so which the phase matching is disturbed, and thermal lensing may perhaps occur
Superior Damage Threshold: BIBO crystal includes a large damage threshold, allowing it to withstand substantial laser ability devoid of suffering harm. This characteristic would make BIBO suited to use in high-electric power laser techniques.
