Hygroscopic crystal materials deteriorate when they are not usually retained in adequately dry air (or maybe a dry purge gas). This is applicable e.g. to KDP and BBO, and in a lesser extent to LBO. It might be useful to keep such a crystal in a rather elevated temperature, which makes it much easier to preserve it dry.
Kingwin Optics provides substantial-high quality BIBO crystal with Highly developed coatings and mounting alternatives, rendering it a superb option for scientists, engineers, and makers looking for successful and reputable nonlinear optical components.
BiB3O6 (BIBO) is an excellent kind of nonlinear Optical Crystal. NLO Crystals BIBO Crystals possesses substantial efficient nonlinear coeffcient, extensive Innovative attribute for the NLO application broad transparency vary from 286nm to 2500nm, high damage threshold and inertness with regard to moisture.
With a substantial effective nonlinear coefficient, significant damage threshold, and inertness to moisture, BIBO crystal presents a number of pros above other nonlinear optical elements for instance LBO and BBO.
Both equally have a relatively small harm threshold, but tend not to must be operated at high intensities due to their higher nonlinearity. They've got a bent for photorefractive results, which might be harmful for frequency conversion, but are used for, e.g., holographic data storage in Fe-doped LiNbO3 crystals. The inclination for “photorefractive damage�?is dependent strongly on the material composition; e.g. it might be diminished by means of MgO doping and by utilizing a stoichiometric composition.
Even when the crystal substance or coating is just not delicate to h2o, tiny drinking water droplets may well concentration laser radiation a lot more tightly than less than regular Procedure, and so hurt the crystal product.
Filters under or the form at the bottom may be used to help item lookup or make even more inquiries.
Operation of nonlinear crystals at temperatures below area temperature (to accomplish phase matching) is mostly problematic, as it could produce condensation of drinking water on the crystal surfaces if the surrounding air is not really pretty dry.
Although the nonlinear coefficient of KTP crystal is massive, the laser harm threshold is very low, which can induce troubles such as refractive index change and transmission reduction. BIBO crystal has better laser damage threshold and better 2nd harmonic conversion performance. Although LBO and B-BBO are the most sensible, These are small in measurement and have particular hygroscopicity, though BIBO crystals are non-moist and may mature to massive size. These benefits permit BIBO crystals to generally be extensively utilised.
Too much optical intensities all through operation might immediately injury a crystal. However, nonlinear crystals normally have to be operated not far from their optical injury threshold to obtain a sufficiently significant conversion effectiveness. This suggests a trade-off amongst conversion effectiveness and crystal life span.
In several conditions, a nonlinear crystal employed for nonlinear frequency conversion has an exceptionally prolonged life time, which happens to here be for a longer period than that of The entire laser system. The crystal substance is essentially not modified during operation. Having said that, a decreased crystal life span can take place under many situations:
GWU-Lasertechnik provides all regular nonlinear crystals like LBO, BBO and KTP using a wide number of specs. Beside the very well-founded products, impressive crystals like CLBO or BiBO with excellent Attributes for e. g. deep-UV generation or higher-electric power ultrashort pulse lasers are available. Irrespective of if specific parts for R & D reasons are required or Charge-economical quantities in compact, medium or significant batches with in-time shipping and delivery with the generation line are desired: GWU’s dedicated services helps you to locate the finest Main elements for the software.
Optical crystals can show different sorts of optical nonlinearities, that may be used in numerous techniques:
Given that the second harmonic (SHG) can be greatly accustomed to make coherent obvious light-weight and ultraviolet radiation, people concentrate to it, but the traditional nonlinear crystals which include KDP, LBO, KTP, B-BBO also have lots of shortcomings. BIBO crystal is a whole new kind of nonlinear crystal. As opposed with KDP crystal, it helps make up with the drawback that KDP crystal can mature in huge sizing but dissolve in drinking water.
