If you don't locate the appropriate products above, it's possible you'll let us know your demands or programs in the shape down below. Our sales or technical employees will get back to you personally at the earliest opportunity.

If the crystal surfaces are still “dirty�?immediately after the above cleaning processes, the surfaces may need been weakened. Please contact us for rework on the crystals.

Inspect the crystal surface area for dust and stains by Keeping it in the vicinity of a dazzling noticeable-gentle supply. Viewing at distinct angles will help see scattering from dust and stains. The crystal floor needs to be cleaned as described under if dust and stains are found.

The level of the solvent is usually modified for a variety of crystal dimension Therefore the lens tissue is kept moist for the whole drag but there's not any obvious trace of solvent about the crystal surface following the drag is concluded. Inspect the surface and repeat if required, but only use Just about every sheet of lens tissue once.

The two have a comparatively reduced problems threshold, but do not have to be operated at significant intensities due to their large nonlinearity. They may have a tendency for photorefractive results, which are detrimental for frequency conversion, but are utilized for, e.g., holographic info storage in Fe-doped LiNbO3 crystals. The inclination for “photorefractive damage�?is dependent strongly on the fabric composition; e.g. it might be decreased through MgO doping and by making use of a stoichiometric composition.

Even though the crystal material or coating is not really sensitive to drinking water, small h2o droplets might focus laser radiation additional tightly than below regular Procedure, and therefore harm the crystal product.

Filters underneath or the shape at The underside may be used to assist item research or make additional inquiries.

Procedure of nonlinear crystals at temperatures underneath place temperature (to accomplish period matching) is normally problematic, as it may well produce condensation of h2o about the crystal surfaces In case the encompassing air isn't pretty dry.

In the case of ultrashort pulses the large group velocity mismatch enforces using a shorter crystal, which involves significant optical intensities for any presented conversion efficiency.

Too much optical intensities all through operation may perhaps instantaneously injury a crystal. However, nonlinear crystals frequently need to be operated not significantly from their optical injury threshold to attain a sufficiently large conversion efficiency. This means a trade-off involving conversion effectiveness and crystal life span.

  )  to blow off dust along with other free contaminants 1st. If a dry nitrogen line check here is out there within the lab, an air gun will also be used  to blow absent dust particles. Blow off the surface area gently. Tend not to blow off the crystal itself from your hand!

GWU-Lasertechnik provides all normal nonlinear crystals like LBO, BBO and KTP that has a wide variety of specs. Beside the effectively-proven supplies, modern crystals like CLBO or BiBO with remarkable Attributes for e. g. deep-UV generation or high-electrical power ultrashort pulse lasers can be found. It does not matter if particular person parts for R & D applications are demanded or Price tag-economical quantities in compact, medium or significant batches with in-time supply with the generation line are wanted: GWU’s committed provider helps you to find the very best core factors on your application.

The Coating curves, transmittance curves, flatness stories and surface area quality report underneath microscope for BiBO Crystal will likely be provided when delivered.

Considering that the second harmonic (SHG) is usually commonly accustomed to generate coherent seen mild and ultraviolet radiation, people today concentrate to it, but the traditional nonlinear crystals which include KDP, LBO, KTP, B-BBO even have quite a few shortcomings. BIBO crystal is a fresh sort of nonlinear crystal. Compared with KDP crystal, it helps make up with the drawback that KDP crystal can increase in substantial dimension but dissolve in h2o.
