Hygroscopic crystal resources deteriorate when they are not constantly stored in adequately dry air (or possibly a dry purge gas). This is applicable e.g. to KDP and BBO, and in a lesser extent to LBO. It could be beneficial to keep this type of crystal in a considerably elevated temperature, that makes it easier to retain it dry.
If the crystal surfaces remain “dirty�?soon after the above mentioned cleaning techniques, the surfaces might have been ruined. Be sure to Make contact with us for rework with the crystals.
five mm to reduce group velocity mismatch and are perfect for frequency doubling or tripling of Ti:sapphire and Yb:doped laser pulses. The vital and noncritical section matching LBO crystals are perfect for second or third harmonic technology of Nd:YAG and Yb:doped lasers.
Typically, the crystal product must have a higher optical transparency for all wavelengths concerned �?such as, for pump, signal and idler within an optical parametric amplifier.
Equally have a relatively small hurt threshold, but never need to be operated at superior intensities because of their higher nonlinearity. They've a tendency for photorefractive consequences, which might be harmful for frequency conversion, but are useful for, e.g., holographic knowledge storage in Fe-doped LiNbO3 crystals. The inclination for “photorefractive damage�?depends strongly on the material composition; e.g. it could be diminished via MgO doping and through the use of a stoichiometric composition.
Dust and stains on crystal surfaces could cause scattering/decline of light and may even respond with gentle to break optical surfaces at a substantial incident laser electrical power.
Lithium niobate (LiNbO3) and lithium tantalate (LiTaO3) are products with a comparatively strong nonlinearity. They are often useful for nonlinear frequency conversion and likewise for electro-optic modulators. Both equally materials are available in congruent As well as in stoichiometric variety, with crucial variances relating to periodic poling and photorefractive effects (see under). more info Lithium niobate and tantalate are definitely the most frequently employed products in the context of periodic poling; the ensuing products are referred to as PPLN (periodically poled lithium niobate) and PPLT, respectively, or PPSLN and PPSLT with the stoichiometric variations.
Bismuth Triborate (BiB3O6 or BIBO) can be a freshly made nonlinear optical crystal. It possesses substantial successful nonlinear coefficient, higher harm threshold and inertness with regard to dampness.
They exhibit superior homogeneity over big volumes and also have a significant harm threshold, but are hygroscopic and have a reduced nonlinearity.
Abnormal optical intensities for the duration of Procedure might instantly hurt a crystal. Regrettably, nonlinear crystals usually need to be operated not far from their optical destruction threshold to attain a adequately large conversion performance. This means a trade-off in between conversion effectiveness and crystal life time.
In many circumstances, a nonlinear crystal utilized for nonlinear frequency conversion has an incredibly very long life span, which happens to be for a longer time than that of The complete laser program. The crystal material is essentially not modified all through Procedure. However, a lessened crystal lifetime can occur beneath a variety of conditions:
The load on the solvent will trigger the lens tissue to return into contact with the crystal surface area. Bit by bit but steadily drag the moist lens tissue throughout the crystal floor staying thorough not to raise the lens tissue off of your floor. Proceed dragging the lens tissue till it can be off on the surface.
The Coating curves, transmittance curves, flatness studies and floor high-quality report below microscope for BiBO Crystal is going to be delivered when shipped.
Our crystals are used in a wide range of purposes, including different forms of nonlinear frequency conversion and electro-optics, but will also quantum technology.
