BIBO crystal (bismuth triborate) is a comparatively novel nonlinear content in comparison with BBO and LBO crystals. BIBO crystal surpasses BBO with regards to its helpful nonlinearity, when also providing a broader bandgap in comparison to KTP crystal.
In addition, it has an essential application in efficient generation of ultrabright entangled photons by means of blue pumped spontaneous parametric down conversions (SPDC).

Commonly, the crystal product ought to have a superior optical transparency for all wavelengths involved �?for instance, for pump, sign and idler within an optical parametric amplifier.

Even though the crystal material or coating is not delicate to water, compact drinking water droplets might emphasis laser radiation more tightly than less than regular operation, and thus hurt the crystal materials.
Observe that although the nominal intensity is under the nominal damage threshold, there might be difficulties as a result of fluctuations while in the beam electricity or nearby depth (e.g., if a beam profile has “incredibly hot spots�?, or due to isolated defects in a very crystal, that happen to be a lot more sensitive when compared to the standard crystal material.
And is especially advantageous for making wavelengths in the inexperienced and blue spectrum through constant-wave (CW) radiation. The elevated helpful nonlinearity of BIBO crystal not just improves the performance from the SHG course of action but also facilitates the utilization of shorter crystal lengths—an indispensable attribute when endeavoring to engineer compact laser techniques.
They show excellent homogeneity around huge volumes and possess a higher problems threshold, but are hygroscopic and have a low nonlinearity.
Excessive optical intensities throughout operation may perhaps instantly destruction a crystal. Regretably, nonlinear crystals generally must be operated not much from their optical injury threshold to attain a adequately significant conversion effectiveness. This implies a trade-off between conversion performance and crystal life time.
Non-linear Optical (NLO) crystals give an enormously flexible Answer for producing new wavelengths from present, off-the-shelf laser sources. The optical wavelength spectrum is used by a large and get more info regularly expanding selection of programs, from production of health care lasers, quantum networking & computing by to environmental sensing and lots of Many others.
GWU-Lasertechnik offers all conventional nonlinear crystals like LBO, BBO and KTP that has a broad range of technical specs. Beside the well-set up components, progressive crystals like CLBO or BiBO with outstanding properties for e. g. deep-UV generation or superior-ability ultrashort pulse lasers are offered. It does not matter if unique parts for R & D uses are required or Price-efficient numbers in small, medium or huge batches with in-time supply for the production line are desired: GWU’s dedicated company helps to discover the very best core components on your application.
Optical crystals can show distinct styles of optical nonlinearities, which may be used in different methods:
Our crystals are Utilized in a wide range of purposes, which include different varieties of nonlinear frequency conversion and electro-optics, but additionally quantum technology.
