Hygroscopic crystal components deteriorate when they're not often saved in adequately dry air (or a dry purge fuel). This is applicable e.g. to KDP and BBO, As well as in a lesser extent to LBO. It can be practical to maintain this type of crystal in a rather elevated temperature, that makes it much easier to preserve it dry.
If the crystal surfaces remain “filthy�?after the above mentioned cleansing procedures, the surfaces might have been broken. Be sure to Call us for rework from the crystals.

The quantity of the solvent can be adjusted for many crystal dimensions Therefore the lens tissue is saved damp for the whole drag but there is not any obvious trace of solvent within the crystal area after the drag is finished. Inspect the floor and repeat if necessary, but only use Just about every sheet of lens tissue when.
BIBO crystals can be utilized as higher-efficiency frequency doubling and frequency summing gadgets and also have wide application potential clients in optical parametric oscillation (OPO).
Dust and stains on crystal surfaces could potentially cause scattering/reduction of sunshine and can even respond with mild to damage optical surfaces in a higher incident laser power.
The choice on the most fitted crystal material for any supplied software is commonly much from trivial; it really should contain the thing to consider of numerous areas. One example is, a superior nonlinearity for frequency conversion of ultrashort pulses does not help When the interaction duration is strongly confined by a considerable team velocity mismatch plus the lower hurt threshold limitations the relevant optical intensities.
Operation of nonlinear crystals at temperatures down below place temperature (to accomplish stage matching) is normally problematic, as it could produce condensation of drinking water about the crystal surfaces if the bordering air will not be incredibly dry.
rystal surface is horizontal and somewhat over check here your fingers. Take a refreshing, clear sheet of lens tissue and spot it within the crystal. Ensure the lens tissue may be drawn across the crystal floor. Following, location a little drop of pure isopropyl alcohol (IPA) to the lens tissue along with the crystal area.
Numerous properties of a nonlinear crystal can be essential for an application e.g. in nonlinear frequency conversion:
) to blow off dust and other unfastened contaminants initial. If a dry nitrogen line is accessible in the lab, an air gun will also be applied to blow away dust particles. Blow from the surface area Carefully. Do not blow from the crystal itself from the hand!

Substantial electricity laser program: BIBO crystals are ideal for use in higher-power laser units because of their large harm threshold as well as their capacity to withstand significant-intensity laser beams without hurt. This gives BIBO crystals a significant edge in laser applications that have to have higher Electrical power output.
flux-developed KTP and RTP with its superior nonlinearity, also in variants with high grey monitoring resistance
