Hygroscopic crystal resources deteriorate when they're not always held in adequately dry air (or possibly a dry purge fuel). This is applicable e.g. to KDP and BBO, and in a lesser extent to LBO. It could be valuable to maintain this kind of crystal in a somewhat elevated temperature, which makes it easier to retain it dry.
If the crystal surfaces are still “dirty�?right after the above cleaning techniques, the surfaces may have been harmed. Be sure to Make contact with us for rework on the crystals.
Inspect the crystal surface area for dust and stains by Keeping it in close proximity to a vivid visible-light-weight supply. Viewing at different angles might help see scattering from dust and stains. The crystal area must be cleaned as explained under if dust and stains are found.
Normally, the crystal substance should have a large optical transparency for all wavelengths included �?one example is, for pump, sign and idler within an optical parametric amplifier.
Also, it could be very desirable to work with a crystal material which may be critically period-matched at home temperature since noncritical period matching often requires the Procedure of the crystal within a temperature-stabilized crystal oven. Even so, the feasibility of significant section matching may be offered only for sufficiently higher peak powers.
Even if the crystal material or coating is not delicate to drinking water, smaller drinking water droplets could concentrate laser radiation much more tightly than beneath typical Procedure, and thus damage the crystal substance.
At present, as A form of fantastic nonlinear 2nd harmonic crystal, it can be utilized to produce significant efficiency crystal of environmentally friendly or blue laser.
Bismuth Triborate (BiB3O6 or BIBO) can be a newly created nonlinear optical crystal. It possesses substantial helpful nonlinear coefficient, significant problems threshold and inertness with regard to dampness.
Although the nonlinear coefficient of KTP crystal is substantial, the laser problems threshold is reduced, which is able to lead to problems including refractive index improve and transmission loss. BIBO crystal has larger laser problems threshold and better next harmonic conversion efficiency. Though LBO and B-BBO are quite possibly the most sensible, they are little in measurement and also have specified hygroscopicity, though BIBO crystals are non-wet and can grow to large size. These benefits enable BIBO crystals to be greatly made use of.
Extreme optical intensities throughout Procedure could immediately destruction a crystal. However, nonlinear crystals frequently must be operated not far from their optical problems threshold to attain a adequately high conversion efficiency. This means a trade-off between conversion efficiency and crystal life time.
Non-linear Optical (NLO) crystals provide an enormously versatile Alternative for producing new wavelengths from current, off-the-shelf laser sources. The optical wavelength spectrum is utilized by a substantial and constantly increasing range of apps, from production of clinical lasers, quantum networking & computing as a result of to environmental sensing and lots of Many others.
GWU-Lasertechnik offers all common nonlinear crystals like LBO, BBO and KTP with a wide range check here of specs. Beside the well-established elements, revolutionary crystals like CLBO or BiBO with outstanding properties for e. g. deep-UV technology or superior-ability ultrashort pulse lasers can be found. Despite if unique parts for R & D applications are expected or Expense-successful numbers in little, medium or massive batches with in-time supply for your output line are essential: GWU’s focused provider helps to discover the best Main parts for your personal software.
The magnitude of your efficient nonlinear coefficient is dependent upon the nonlinear tensor parts and to the used period-matching configuration. A substantial nonlinearity is significant significantly Should the achievable optical intensities are very low.
flux-developed KTP and RTP with its substantial nonlinearity, also in variants with substantial gray tracking resistance
