The susceptibility to moisture of BiBO is extremely reduced. Nevertheless, users are encouraged to offer dry problems for each use and storage of BiBO to prolong the lifetime. Water condensation on crystal surfaces really should be Definitely averted Anytime.
If the crystal surfaces are still “dirty�?right after the above cleaning procedures, the surfaces might have been damaged. Be sure to contact us for rework of the crystals.

Generally, the crystal substance ought to have a large optical transparency for all wavelengths associated �?such as, for pump, sign and idler within an optical parametric amplifier.
Artifex Engineering supplies concluded crystal optics for non-linear apps. Take a look at our merchandise webpage for more information. We look forward to your inquiry.
Regardless of whether the crystal content or coating just isn't delicate to drinking water, little h2o droplets may possibly target laser radiation more tightly than underneath typical operation, and therefore harm the crystal product.
Lithium niobate (LiNbO3) and lithium tantalate (LiTaO3) are supplies with a relatively robust nonlinearity. They in many cases are useful for nonlinear frequency conversion in addition to for electro-optic modulators. Both supplies are available in congruent and in stoichiometric kind, with vital differences regarding periodic poling and photorefractive results (see under). Lithium niobate and tantalate are classified as the most often employed components inside the context of periodic poling; the resulting supplies are known as PPLN (periodically poled lithium niobate) and PPLT, respectively, or PPSLN and PPSLT for the stoichiometric variations.
And is especially advantageous for making wavelengths in the inexperienced and blue spectrum through continual-wave (CW) radiation. The elevated effective nonlinearity of BIBO crystal don't just improves the efficiency of the SHG course of action and also facilitates the utilization of shorter crystal lengths—an indispensable attribute when endeavoring to engineer compact laser systems.
In summary, BIBO crystal is usually a promising nonlinear optical content with exceptional Homes which make it suitable for a wide range of optical programs.
Abnormal optical intensities through operation might quickly damage a crystal. Sad to say, nonlinear crystals generally should be operated not far from their optical harm threshold to attain a sufficiently superior conversion effectiveness. This means a trade-off concerning conversion performance and crystal life span.
In lots of circumstances, a nonlinear crystal utilized for nonlinear frequency conversion has an exceptionally very long life here time, that is lengthier than that of The complete laser process. The crystal content is essentially not modified all through operation. Nevertheless, a lessened crystal life time can happen less than a variety of situations:
This combination makes BIBO crystal extremely suited to harnessing the phenomenon of second harmonic technology (SHG) in just stable-condition lasers and laser diodes.
The magnitude from the productive nonlinear coefficient is determined by the nonlinear tensor factors and within the used phase-matching configuration. A significant nonlinearity is essential specially When the achievable optical intensities are very low.
