BIBO crystal (bismuth triborate) is a comparatively novel nonlinear material when put next with BBO and LBO crystals. BIBO crystal surpasses BBO with regards to its powerful nonlinearity, even though also supplying a broader bandgap in comparison to KTP crystal.
Laser processing and product dealing with: In the sector of laser processing and content dealing with, the significant energy capability of BIBO crystals can make them a key ingredient from the manufacture of higher Electrical power density laser beams.
Inspect the crystal surface for dust and stains by holding it around a brilliant visible-mild resource. Viewing at unique angles can assist see scattering from dust and stains. The crystal surface area has to be cleaned as explained under if dust and stains are discovered.
Crystal lifetime can be strongly depending on the material good quality, although specific degradation phenomena look like intrinsic limitations of the fabric.
BIBO crystals may be used as high-effectiveness frequency doubling and frequency summing equipment and also have wide software potential clients in optical parametric oscillation (OPO).
Be sure to use "Increase to Cart" to position the interesting goods within the shopping cart. Take a look at with on-line payment or inquire us for the costs/availability by using the browsing cart.
The selection on the most suitable crystal material for a presented application is usually significantly from trivial; it must involve the thing to consider of many aspects. As an example, a significant nonlinearity for frequency conversion of ultrashort pulses does not assist Should the conversation duration is strongly limited by a sizable group velocity mismatch and the reduced hurt threshold restrictions the applicable optical intensities.
And is especially advantageous for producing wavelengths inside the environmentally friendly and blue spectrum through ongoing-wave (CW) radiation. The elevated efficient nonlinearity of BIBO crystal not simply boosts the efficiency with the SHG process but in addition facilitates the utilization of shorter crystal lengths—an indispensable attribute when endeavoring to engineer compact laser units.
They exhibit excellent homogeneity in excess of substantial volumes and have a significant harm threshold, but are hygroscopic and possess a reduced nonlinearity.
A number of Qualities of the nonlinear crystal might be essential for an software e.g. in nonlinear frequency conversion:
) to blow off dust as well as other unfastened contaminants to start with. If a dry nitrogen line is available in the lab, an air gun can also be used to blow absent dust particles. Blow from the floor gently. Tend not to blow off the crystal itself from your hand!

Optical crystals can show different varieties of optical nonlinearities, which can be utilized in many methods:
Significant Damage Threshold: BIBO crystal contains a higher damage threshold, letting it to withstand higher laser energy without struggling destruction. This characteristic would make more info BIBO ideal for use in large-ability laser systems.
