Hygroscopic crystal supplies deteriorate when they are not generally saved in sufficiently dry air (or possibly a dry purge gasoline). This is applicable e.g. to KDP and BBO, As well as in a lesser extent to LBO. It can be beneficial to help keep this type of crystal in a rather elevated temperature, which makes it much easier to preserve it dry.
If the crystal surfaces are still “filthy�?soon after the above cleansing techniques, the surfaces may need been damaged. Be sure to Make contact with us for rework from the crystals.
Inspect the crystal surface for dust and stains by holding it in the vicinity of a shiny noticeable-light-weight supply. Viewing at unique angles may also help see scattering from dust and stains. The crystal floor has to be cleaned as described below if dust and stains are identified.
Normally, the crystal content ought to have a large optical transparency for all wavelengths included �?for instance, for pump, sign and idler within an optical parametric amplifier.
BIBO crystals can be employed as significant-effectiveness frequency doubling and frequency summing equipment and have wide application prospective clients in optical parametric oscillation (OPO).
GWU-Lasertechnik has more than 30 years of practical experience in distributing laser crystals. Pick GWU to benefit from our extensive knowledge and in-subject working experience!
Note that whether or not the nominal depth is below the nominal destruction threshold, there may be difficulties as a consequence of fluctuations within the beam electrical power or regional depth (e.g., if a beam profile has “incredibly hot places�?, or resulting from isolated defects inside of a crystal, which are more delicate than the standard crystal substance.
Bismuth Triborate (BiB3O6 or BIBO) is actually a recently designed nonlinear optical crystal. It possesses massive productive nonlinear coefficient, substantial hurt threshold and inertness with respect to moisture.
Even though the nonlinear coefficient of KTP crystal is huge, the laser harm threshold is minimal, which is able to result in complications for example refractive index improve and transmission loss. BIBO crystal has increased laser harm threshold and better next harmonic conversion efficiency. Despite the fact that LBO and B-BBO are probably the most functional, They're tiny in dimensions and possess sure hygroscopicity, while BIBO crystals are non-wet and can develop to big dimension. These positive aspects empower BIBO crystals to generally be greatly made use of.
Abnormal optical intensities for the duration of operation may perhaps promptly injury a crystal. Sadly, nonlinear crystals often should be operated not much from their optical damage threshold to accomplish a sufficiently substantial conversion performance. This implies a trade-off involving conversion efficiency and crystal life time.
) to blow off dust and various unfastened contaminants 1st. If a dry nitrogen line is offered while in the lab, an air gun may also be utilized to blow absent dust particles. Blow off the surface Carefully. Usually do not blow off the crystal by itself from your hand!
芯飞睿所有的服务和支持都立足于使我们的客人工作的更加高效，更有价值。
Substantial electric power laser procedure: BIBO crystals are perfect for use in high-energy laser techniques due to their substantial problems threshold as well as their means to face up to significant-depth laser beams devoid of injury. This offers BIBO crystals an important here edge in laser purposes that have to have large Electricity output.
flux-developed KTP and RTP with its superior nonlinearity, also in variants with superior grey monitoring resistance
