Hygroscopic crystal supplies deteriorate when they are not always retained in sufficiently dry air (or simply a dry purge gas). This is applicable e.g. to KDP and BBO, and in a lesser extent to LBO. It could be useful to maintain this type of crystal at a considerably elevated temperature, which makes it simpler to keep it dry.
Inertness to Moisture: BIBO crystal is inert to humidity, meaning it does not degrade or lose its optical Qualities when exposed to humidity. This helps make BIBO a more steady and trusted option for optical purposes in several environments.
Many of the conventional nonlinear crystals like BBO, LBO, BiBO or KTP for frequency doubling, tripling and quadrupling of the elemental laser radiation can be obtained from inventory. Consumer-unique Proportions and AR coatings are presented at aggressive price ranges.
Crystal lifetime may also be strongly dependent on the fabric quality, Despite the fact that selected degradation phenomena appear to be intrinsic limitations of the material.
Artifex Engineering supplies completed crystal optics for non-linear purposes. Visit our products webpage To find out more. We look forward to your inquiry.
Regardless of whether the crystal product or coating just isn't delicate to drinking water, modest drinking water droplets may possibly focus laser radiation much more tightly than under ordinary Procedure, and therefore hurt the crystal content.
Lithium niobate (LiNbO3) and lithium tantalate (LiTaO3) are resources with a comparatively solid nonlinearity. They will often be used for nonlinear frequency conversion in addition to for electro-optic modulators. Both elements can be found in congruent As well as in stoichiometric sort, with significant variances about periodic poling and photorefractive outcomes (see beneath). Lithium niobate and tantalate are the most frequently utilised products while in the context of periodic poling; the ensuing products are termed PPLN (periodically poled lithium niobate) and PPLT, respectively, or PPSLN and PPSLT with the stoichiometric variations.
Bismuth Triborate (BiB3O6 or BIBO) is really a freshly designed nonlinear optical crystal. It possesses massive productive nonlinear coefficient, superior destruction threshold and inertness with respect to dampness.
In the case of ultrashort pulses the superior group velocity mismatch enforces using a shorter crystal, which demands superior optical intensities for just a provided conversion effectiveness.
Crystals which happen to be non-critically phase-matched within a crystal oven may possibly website exhibit complications in the event the crystal temperature is changed much too quickly or too normally. Particularly, anti-reflection coatings may be damaged due to distinct thermal growth coefficients of the included products.
Even properly below the brink for instant damage, some crystal components show a continuous degradation inside the used quantity, e.

Optical crystals can show various forms of optical nonlinearities, that may be used in various ways:
Our crystals are used in an array of apps, together with various varieties of nonlinear frequency conversion and electro-optics, but also quantum engineering.
