The susceptibility to dampness of BiBO is extremely small. On the other hand, consumers are suggested to deliver dry situations for both equally use and storage of BiBO to prolong the lifetime. H2o condensation on crystal surfaces must be Totally averted Anytime.
Inertness to Moisture: BIBO crystal is inert to humidity, meaning it does not degrade or shed its optical Homes when exposed to humidity. This would make BIBO a more steady and reputable choice for optical applications in various environments.
Inspect the crystal floor for dust and stains by Keeping it around a brilliant visible-light-weight supply. Viewing at diverse angles may also help see scattering from dust and stains. The crystal floor must be cleaned as described beneath if dust and stains are found.
The level of the solvent is usually modified for different crystal size And so the lens tissue is retained moist for the entire drag but there's not any visible trace of solvent to the crystal surface area once the drag is finished. Inspect the floor and repeat if necessary, but only use Just about every sheet of lens tissue once.
BIBO crystals can be used as large-effectiveness frequency doubling and frequency summing units and possess broad application prospects in optical parametric oscillation (OPO).
Dust and stains on crystal surfaces can result in scattering/loss of sunshine and may even react with light-weight to wreck optical surfaces at a superior incident laser electric power.
The choice from the best suited crystal product to get a presented software is frequently considerably from trivial; it should include the thought of many aspects. For example, a large nonlinearity for frequency conversion of ultrashort pulses isn't going to assistance if the conversation duration is strongly restricted by a substantial group velocity mismatch plus the very low problems threshold boundaries the applicable optical intensities.
And is especially useful for making wavelengths during the inexperienced and blue spectrum via continual-wave (CW) radiation. The elevated powerful nonlinearity of BIBO crystal not only improves the efficiency on the SHG system but in addition facilitates the utilization of shorter crystal lengths—an indispensable attribute when endeavoring to engineer compact laser devices.
They show very good homogeneity in excess of huge volumes and also have a higher destruction threshold, but are hygroscopic and also have a minimal nonlinearity.
Many different Qualities of a nonlinear crystal could be critical for an application e.g. in nonlinear frequency conversion:
) to blow off dust and other unfastened contaminants to start with. If a dry nitrogen line is available in the lab, an air gun can even be utilised to blow away dust particles. Blow from the surface area Carefully. Tend not to blow off the BIBO Crystal crystal alone out of your hand!
The burden from the solvent will lead to the lens tissue to return into connection with the crystal area. Little by little but steadily drag the damp lens tissue over the crystal floor currently being thorough never to carry the lens tissue off of your area. Go on dragging the lens tissue till it really is off of the area.
Optical crystals can show distinct kinds of optical nonlinearities, which may be utilized in a variety of methods:
flux-developed KTP and RTP with its superior nonlinearity, also in variants with higher gray monitoring resistance
