Inertness to Dampness: BIBO crystal is inert to dampness, which suggests it doesn't degrade or get rid of its optical Houses when subjected to humidity. This will make BIBO a far more steady and reputable option for optical apps in a variety of environments.
Furthermore, it has an important application in productive technology of ultrabright entangled photons by means of blue pumped spontaneous parametric down conversions (SPDC).
The vast majority of normal nonlinear crystals like BBO, LBO, BiBO or KTP for frequency doubling, tripling and quadrupling of the elemental laser radiation are offered from inventory. Shopper-certain Proportions and AR coatings are also presented at aggressive rates.
Crystal life span may also be strongly depending on the fabric top quality, Even though specific degradation phenomena seem like intrinsic restrictions of the material.
Each have a relatively reduced injury threshold, but usually do not have to be operated at large intensities due to their substantial nonlinearity. They've got a bent for photorefractive outcomes, that happen to be detrimental for frequency conversion, but are employed for, e.g., holographic knowledge storage in Fe-doped LiNbO3 crystals. The tendency for “photorefractive destruction�?is dependent strongly on the fabric composition; e.g. it may be lessened through MgO doping and by using a stoichiometric composition.
GWU-Lasertechnik has a lot more than thirty years of experience in distributing laser crystals. Select GWU to reap the benefits of our extensive information and in-discipline working experience!
Lithium niobate (LiNbO3) and lithium tantalate (LiTaO3) are resources with a relatively robust nonlinearity. They are sometimes utilized for nonlinear frequency conversion as well as for electro-optic modulators. Both materials can be found in congruent and in stoichiometric type, with critical distinctions concerning periodic poling and photorefractive consequences (see under). Lithium niobate and tantalate would be the most frequently utilized elements within the context of periodic poling; the ensuing products are referred to as PPLN (periodically poled lithium niobate) and PPLT, respectively, or PPSLN and PPSLT for that stoichiometric variations.
And is especially beneficial for generating wavelengths from the eco-friendly and blue spectrum through ongoing-wave (CW) radiation. The elevated successful nonlinearity of BIBO crystal not only boosts the efficiency with the SHG method but will also facilitates the utilization of shorter crystal lengths—an indispensable attribute when endeavoring to engineer compact laser devices.
In the situation of ultrashort pulses the substantial group velocity mismatch enforces the use of a shorter crystal, which requires high optical intensities to get a offered conversion performance.
Numerous Attributes of the nonlinear crystal is often important for an application e.g. in nonlinear frequency conversion:
) to blow off dust and also other free contaminants very first. If a dry nitrogen line is obtainable inside the lab, an air gun can even be used to blow absent dust particles. Blow from the surface area gently. Never blow from the crystal itself out of your hand!

Large electrical power laser program: BIBO Crystal BIBO crystals are perfect for use in significant-power laser devices due to their higher damage threshold and their capability to face up to significant-depth laser beams without injury. This provides BIBO crystals a substantial edge in laser apps that involve high Strength output.
Higher Damage Threshold: BIBO crystal has a superior hurt threshold, making it possible for it to withstand superior laser ability with no suffering harm. This attribute would make BIBO appropriate for use in high-electric power laser techniques.
