BIBO crystal (bismuth triborate) is a relatively novel nonlinear materials compared with BBO and LBO crystals. BIBO crystal surpasses BBO concerning its successful nonlinearity, even though also featuring a broader bandgap compared to KTP crystal.
Laser processing and product managing: In the field of laser processing and materials dealing with, the significant power functionality of BIBO crystals helps make them a key element in the manufacture of higher Power density laser beams.

The quantity of the solvent might be modified for numerous crystal size And so the lens tissue is retained damp for the whole drag but there's not any obvious trace of solvent around the crystal area following the drag is completed. Inspect the surface area and repeat if essential, but only use each sheet of lens tissue the moment.
Equally have a relatively small harm threshold, but tend not to need to be operated at large intensities due to their significant nonlinearity. They have a tendency for photorefractive effects, which can be detrimental for frequency conversion, but are used for, e.g., holographic data storage in Fe-doped LiNbO3 crystals. The tendency for “photorefractive injury�?depends strongly on the material composition; e.g. it might be decreased by way of MgO doping and through the use of a stoichiometric composition.
Even though the crystal content or coating will not be delicate to drinking water, compact h2o droplets could emphasis laser radiation far more tightly than beneath standard operation, and thus harm the crystal material.
Filters below or the shape at the bottom can be used to aid products look for or make even further inquiries.
And is especially advantageous for building wavelengths from the eco-friendly and blue spectrum as a result of constant-wave (CW) radiation. The elevated efficient nonlinearity of BIBO crystal not simply enhances the effectiveness of the SHG approach but also facilitates the utilization of shorter crystal lengths—an indispensable attribute when endeavoring to engineer compact laser techniques.
Although the nonlinear coefficient of KTP crystal is large, the laser problems threshold is minimal, which will bring about difficulties which include refractive index modify and transmission decline. BIBO crystal has higher laser problems threshold and higher 2nd harmonic conversion effectiveness. Although LBO and B-BBO are by far the most sensible, They can be compact in dimension and also have specified hygroscopicity, though BIBO crystals are non-wet and can develop to huge dimension. These positive aspects allow BIBO crystals for being broadly utilised.
the chemical sturdiness; e.g., some crystal elements are hygroscopic, Other individuals bear chemical improvements when heated inside a vacuum chamber for application of a dielectric coating
Even perfectly underneath the threshold for fast injury, more info some crystal materials exhibit a continuous degradation in the used quantity, e.
GWU-Lasertechnik offers all typical nonlinear crystals like LBO, BBO and KTP using a wide selection of technical specs. Beside the effectively-established elements, progressive crystals like CLBO or BiBO with superb Qualities for e. g. deep-UV era or higher-electricity ultrashort pulse lasers are offered. Regardless of if particular person items for R & D uses are required or Price-productive figures in modest, medium or substantial batches with in-time supply for that output line are desired: GWU’s focused company helps to locate the most effective Main parts for the software.
The magnitude in the successful nonlinear coefficient relies on the nonlinear tensor components and around the utilized stage-matching configuration. A large nonlinearity is significant significantly if the achievable optical intensities are reduced.
Our crystals are used in a wide range of programs, including a variety of styles of nonlinear frequency conversion and electro-optics, but in addition quantum technology.
