Hygroscopic crystal materials deteriorate when they are not usually held in sufficiently dry air (or perhaps 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 at a rather elevated temperature, that makes it much easier to retain it dry.
If the crystal surfaces are still “filthy�?just after the above cleaning methods, the surfaces might need been damaged. You should Call us for rework of your crystals.

The amount of the solvent is usually modified for various crystal sizing Therefore the lens tissue is stored moist for the whole drag but there is not any obvious trace of solvent about the crystal area following the drag is concluded. Inspect the surface and repeat if needed, but only use Every sheet of lens tissue at the time.
BIBO crystals may be used as higher-effectiveness frequency doubling and frequency summing equipment and possess wide software potential clients in optical parametric oscillation (OPO).
Even when the crystal material or coating isn't delicate to h2o, smaller drinking water droplets may possibly target laser radiation a lot more tightly than under ordinary Procedure, and thus harm the crystal product.
The choice on the most fitted crystal material for any supplied software is commonly far from trivial; it ought to entail the thought of numerous features. By way of example, a superior nonlinearity for frequency conversion of ultrashort pulses will not aid In more info case the interaction length is strongly restricted by a sizable group velocity mismatch and the low destruction threshold boundaries the applicable optical intensities.
Procedure of nonlinear crystals at temperatures under room temperature (to achieve stage matching) is mostly problematic, as it may well bring about condensation of drinking water over the crystal surfaces When the encompassing air will not be pretty dry.
rystal surface area is horizontal and a bit earlier mentioned your fingers. Have a clean, clear sheet of lens tissue and spot it within the crystal. Ensure the lens tissue may be drawn across the crystal area. Following, spot a small drop of pure isopropyl Alcoholic beverages (IPA) over the lens tissue along with the crystal surface.
Crystals which happen to be non-critically section-matched inside of a crystal oven may perhaps show troubles once the crystal temperature is modified as well quickly or too normally. Specifically, anti-reflection coatings may very well be damaged due to various thermal enlargement coefficients on the involved elements.
Non-linear Optical (NLO) crystals offer an enormously versatile Resolution for making new wavelengths from present, off-the-shelf laser resources. The optical wavelength spectrum is used by a large and regularly expanding selection of purposes, from manufacturing of healthcare lasers, quantum networking & computing by means of to environmental sensing along with several Other individuals.
This mix would make BIBO crystal exceptionally fitted to harnessing the phenomenon of 2nd harmonic generation (SHG) within just reliable-state lasers and laser diodes.
linear absorption, which often can trigger heating at significant optical electrical power concentrations, so that the stage matching is disturbed, and thermal lensing may perhaps take place
Substantial Hurt Threshold: BIBO crystal incorporates a substantial injury threshold, permitting it to resist large laser energy with out struggling hurt. This characteristic will make BIBO suited to use in large-power laser devices.
