Hygroscopic crystal components deteriorate when they are not normally retained in sufficiently 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 might be helpful to keep such a crystal at a to some degree elevated temperature, that makes it simpler to continue to keep it dry.
Inertness to Humidity: BIBO crystal is inert to moisture, which suggests it does not degrade or lose its optical Houses when subjected to humidity. This would make BIBO a far more stable and dependable selection for optical applications in different environments.
BiB3O6 (BIBO) is a superb sort of nonlinear Optical Crystal. NLO Crystals BIBO Crystals possesses big productive nonlinear coeffcient, vast Superior attribute to the NLO application broad transparency vary from 286nm to 2500nm, high problems threshold and inertness with regard to dampness.
Crystal life time will also be strongly dependent on the fabric high quality, Whilst particular degradation phenomena look like intrinsic limits of the material.
BIBO crystals can be employed as large-efficiency frequency doubling and frequency summing products and also have broad software prospective clients in optical parametric oscillation (OPO).
GWU-Lasertechnik has in excess of 30 years of knowledge in distributing laser crystals. Pick out GWU to take advantage of our extensive expertise and in-subject encounter!
The choice in the best suited crystal content for just a given application is usually far from trivial; it ought to entail the thing to consider of many factors. Such as, a higher nonlinearity for frequency conversion of ultrashort pulses will not assistance In the event the interaction size is strongly limited by a sizable team velocity mismatch as well as low injury threshold boundaries the applicable optical intensities.
Bismuth Triborate (BiB3O6 or BIBO) is usually a newly created nonlinear optical crystal. It possesses huge successful nonlinear coefficient, substantial hurt threshold and inertness with respect to dampness.
They show very good homogeneity around huge volumes and possess a large hurt threshold, but are hygroscopic and have a lower nonlinearity.
A variety of Attributes of a nonlinear crystal can be significant for an application e.g. in nonlinear frequency conversion:
In many situations, a nonlinear crystal employed for nonlinear frequency conversion has an exceedingly lengthy lifetime, which happens to be for a longer time than that of The complete laser program. The crystal product is actually not modified during operation. Having said that, a lessened crystal life time can take place underneath many situations:
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。
The magnitude in the productive nonlinear coefficient is dependent upon the nonlinear tensor elements and to the website used phase-matching configuration. A substantial nonlinearity is essential especially In case the achievable optical intensities are lower.
Considering the fact that the 2nd harmonic (SHG) is often extensively used to deliver coherent seen gentle and ultraviolet radiation, people concentrate to it, but the standard nonlinear crystals which include KDP, LBO, KTP, B-BBO also have lots of shortcomings. BIBO crystal is a brand new variety of nonlinear crystal. Compared with KDP crystal, it helps make up for your drawback that KDP crystal can develop in substantial dimension but dissolve in h2o.
