BIBO crystal (bismuth triborate) is a relatively novel nonlinear content in comparison with BBO and LBO crystals. BIBO crystal surpasses BBO with regard to its powerful nonlinearity, although also providing a broader bandgap compared to KTP crystal.
If the crystal surfaces remain “dirty�?after the above mentioned cleaning strategies, the surfaces may have been weakened. Please Call us for rework of the crystals.
Inspect the crystal surface for dust and stains by holding it in the vicinity of a shiny obvious-mild source. Viewing at unique angles may also help see scattering from dust and stains. The crystal surface area has to be cleaned as explained beneath if dust and stains are observed.
The level of the solvent may be modified for several crystal dimensions Therefore the lens tissue is held moist for the whole drag but there's not any obvious trace of solvent on the crystal surface after the drag is finished. Inspect the surface area and repeat if needed, but only use Each individual sheet of lens tissue once.
Both have a relatively low harm threshold, but usually do not should be operated at superior intensities due to their higher nonlinearity. They have a bent for photorefractive consequences, which are harmful for frequency conversion, but are useful for, e.g., holographic details storage in Fe-doped LiNbO3 crystals. The tendency for “photorefractive problems�?is dependent strongly on the material composition; e.g. it may be lessened by using MgO doping and by making use of a stoichiometric composition.
Employing our marketing deal, you may Show your emblem, further more under your merchandise description, and these will been noticed by a lot of photonics industry experts.
Observe that regardless of whether the nominal depth is underneath the nominal hurt threshold, there might be issues due to fluctuations in the beam ability or nearby intensity (e.g., if a beam profile has “very hot spots�?, or resulting from click here isolated defects within a crystal, which might be much more sensitive compared to the frequent crystal substance.
Operation of nonlinear crystals at temperatures down below place temperature (to accomplish stage matching) is generally problematic, as it may well cause condensation of water around the crystal surfaces If your encompassing air isn't extremely dry.
In the situation of ultrashort pulses the superior team velocity mismatch enforces the use of a shorter crystal, which demands large optical intensities for any specified conversion performance.
Borates for instance LBO and BBO also operate effectively in broadly tunable optical parametric oscillators and optical parametric chirped-pulse amplification.
) to blow off dust and other loose contaminants first. If a dry nitrogen line is offered in the lab, an air gun can also be applied to blow away dust particles. Blow from the floor Carefully. Usually do not blow from the crystal by itself out of your hand!
The load of the solvent will bring about the lens tissue to come into contact with the crystal area. Little by little but steadily drag the damp lens tissue throughout the crystal surface area remaining mindful never to carry the lens tissue off of your floor. Continue dragging the lens tissue right up until it really is off of your surface area.
The Coating curves, transmittance curves, flatness studies and area good quality report under microscope for BiBO Crystal are going to be offered when transported.
Large Harm Threshold: BIBO crystal features a higher destruction threshold, letting it to resist large laser power without the need of struggling injury. This characteristic would make BIBO appropriate for use in higher-electrical power laser systems.
