If you do not locate the appropriate products and solutions over, it's possible you'll let's know your requirements or applications in the form beneath. Our revenue or specialized workers will get back again for you as soon as possible.
If the crystal surfaces are still “dirty�?right after the above mentioned cleansing strategies, the surfaces might need been harmed. Be sure to Call us for rework with the crystals.

Normally, the crystal content ought to have a high optical transparency for all wavelengths associated �?one example is, for pump, sign and idler within an optical parametric amplifier.

GWU-Lasertechnik has in excess of 30 yrs of expertise in distributing laser crystals. Pick out GWU to gain from our wide information As well as in-industry expertise!
The selection in the best suited crystal material for any specified application is usually significantly from trivial; it should really include the thought of numerous aspects. As an example, a large nonlinearity for frequency conversion of ultrashort pulses won't help In the event the interaction length is strongly constrained by a considerable team velocity here mismatch and also the lower problems threshold limits the applicable optical intensities.
Bismuth Triborate (BiB3O6 or BIBO) is often a freshly made nonlinear optical crystal. It possesses big successful nonlinear coefficient, large hurt threshold and inertness with regard to dampness.
They exhibit excellent homogeneity over big volumes and have a higher damage threshold, but are hygroscopic and possess a lower nonlinearity.
the chemical longevity; e.g., some crystal components are hygroscopic, Other folks go through chemical changes when heated inside of a vacuum chamber for application of the dielectric coating
) to blow off dust along with other unfastened contaminants first. If a dry nitrogen line is obtainable inside the lab, an air gun may also be utilised to blow absent dust particles. Blow off the area gently. Will not blow off the crystal alone from a hand!
This combination tends to make BIBO crystal extremely suited to harnessing the phenomenon of next harmonic generation (SHG) inside of reliable-state lasers and laser diodes.
Optical crystals can show various styles of optical nonlinearities, which can be used in various strategies:
Our crystals are used in a wide range of apps, like many sorts of nonlinear frequency conversion and electro-optics, and also quantum technological innovation.
