These raw materials are cautiously measured and blended in exact proportions to ensure the ideal composition of your resulting crystals.
EKSMA Optics uses cookies to provide you with the very best procuring experience. Should you go on to make use of our products and services, we will believe that you choose to conform to using these cookies.
Typical cleaning and suitable storage will help lengthen the lifespan of BBO crystals, guaranteeing their ongoing contribution to the sector of optics and photonics.
As the next harmonic light propagates, its Vitality flows in another path than that of the fundamental light-weight.
Significant-high quality crystals could have much less defects and supply greater overall performance, though a respected provider will stand guiding their merchandise and offer help when needed. Good customer service could also make the getting procedure smoother and much more pleasing.
BBO crystals have two refractive indices: ne for extraordinary rays and no for usual rays. The distinction between ne and no depends on the wavelength of light and also the crystal’s temperature.
Having said that, it’s imperative that you Take note that though BBO crystals can tackle large electricity, they should even now be utilized within just their specified power range to avoid potential damage and guarantee optimum effectiveness.
g. twenty μm. The group velocity mismatch within the thicker substrate product might not click here issue, as the nonlinear interaction takes location only in the thin crystal. The substrate only serves to mechanically stabilize The skinny nonlinear crystal.
We also layer our objects with anti-reflection layers to reduce illustration losses for the crystal surfaces.
By way of example, anti-reflective coatings could be placed on lower gentle loss as a consequence of reflection, whilst protective coatings may be used to improve the crystal’s resistance to environmental aspects. Customization allows for best general performance in distinct purposes.
Furthermore, the structural and compositional characteristics of BBO provide it with remarkable thermal stability and resistance versus environmental issues.
The crystal axis is c. The Main ray is parallel to your route used to evaluate the tuning angle (θ), which happens to be optimized all through phase matching. Conversion performance is optimized for rays parallel on the chief ray and even worse for rays at greater angles (ψ) towards the Main ray.
BBO crystals also have a superior hurt threshold, meaning they might endure significant levels of laser power with no suffering destruction. This is especially significant in programs involving substantial-electric power lasers. Furthermore, BBO crystals Have a very significant nonlinear coefficient, which allows effective frequency conversion, a significant functionality in many optical methods.
Humidity may cause h2o absorption about the crystal surface, which often can degrade its optical functionality. The caliber of the incident gentle, such as its wavelength, intensity, and polarization, could also impact the general performance of BBO crystals in a variety of purposes.
