The susceptibility to humidity of BiBO may be very reduced. Having said that, consumers are recommended to provide dry circumstances for both equally use and storage of BiBO to prolong the lifetime. H2o condensation on crystal surfaces should be Totally avoided Anytime.
Laser processing and content dealing with: In the field of laser processing and materials managing, the significant ability capacity of BIBO crystals would make them a critical part while in the manufacture of large Power density laser beams.
five mm to reduce group velocity mismatch and are ideal for frequency doubling or tripling of Ti:sapphire and Yb:doped laser pulses. The important and noncritical phase matching LBO crystals are ideal for next or 3rd harmonic generation of Nd:YAG and Yb:doped lasers.
Usually, the crystal materials must have a large optical transparency for all wavelengths included �?by way of example, for pump, sign and idler in an optical parametric amplifier.
The two have a relatively small damage threshold, but do not must be operated at substantial intensities because of their significant nonlinearity. They may have an inclination for photorefractive results, which might be detrimental for frequency conversion, but are utilized for, e.g., holographic information storage in Fe-doped LiNbO3 crystals. The tendency for “photorefractive damage�?depends strongly on the material composition; e.g. it can be lowered by way of MgO doping and through the use of a stoichiometric composition.

Filters under or the form at The underside may be used to assist products research or make more inquiries.
Bismuth Triborate (BiB3O6 or BIBO) is usually a freshly formulated nonlinear optical crystal. It possesses substantial productive nonlinear coefficient, significant hurt threshold and inertness with respect to moisture.
They show excellent homogeneity about huge volumes and possess a substantial damage threshold, but are hygroscopic and also have a low nonlinearity.
Many various Homes of a nonlinear crystal could be crucial for an application e.g. in nonlinear frequency conversion:
In lots of circumstances, a nonlinear crystal utilized for nonlinear frequency conversion has a very extended life span, which happens to be for a longer period than that of The complete laser technique. The crystal product is actually not modified during operation. However, a lowered crystal life span can manifest beneath various situations:
This mix can make BIBO crystal exceptionally suited to harnessing the phenomenon of second harmonic era (SHG) inside of good-point out lasers and laser diodes.
Optical crystals can show various varieties of optical nonlinearities, which can be utilized in various strategies:
g. in the shape of “gray tracking�? These types of phenomena are especially prevalent for Procedure with ultraviolet light. Notice that a gradual degradation may lead into instant catastrophic injury by using excessive heat era.
