BIBO crystal (bismuth triborate) is a relatively novel nonlinear content compared with BBO and LBO crystals. BIBO crystal surpasses BBO in terms of its powerful nonlinearity, while also featuring a broader bandgap compared to KTP crystal.
If the crystal surfaces are still “soiled�?following the above cleaning strategies, the surfaces might need been ruined. You should Get hold of us for rework on the crystals.
BiB3O6 (BIBO) is a superb sort of nonlinear Optical Crystal. NLO Crystals BIBO Crystals possesses huge helpful nonlinear coeffcient, wide Innovative characteristic with the NLO software wide transparency range between 286nm to 2500nm, substantial injury threshold and inertness with respect to moisture.
Typically, the crystal materials should have a high optical transparency for all wavelengths involved �?by way of example, for pump, sign and idler in an optical parametric amplifier.
Both have a relatively reduced destruction threshold, but usually do not need to be operated at significant intensities due to their significant nonlinearity. They've a bent for photorefractive consequences, which happen to be detrimental for frequency conversion, but are used for, e.g., holographic details storage in Fe-doped LiNbO3 crystals. The tendency for “photorefractive hurt�?depends strongly on the fabric composition; e.g. it might be diminished via MgO doping and by using a stoichiometric composition.
Dust and stains on crystal surfaces may cause scattering/loss of light and may even react with light to break optical surfaces in a higher incident laser electrical power.
The choice with the best suited crystal material for any given software is usually considerably from trivial; it need to involve the thing to consider of numerous aspects. As an example, a high nonlinearity for frequency conversion of ultrashort pulses won't assist When the conversation length is strongly limited by a significant team velocity mismatch plus the lower hurt threshold limitations the relevant optical intensities.
And is especially beneficial for producing wavelengths in the eco-friendly and blue spectrum through continuous-wave (CW) radiation. The elevated effective nonlinearity of BIBO crystal not merely enhances the efficiency on the SHG course of action but also facilitates the utilization of shorter crystal lengths—an indispensable attribute when endeavoring to engineer compact laser devices.
They exhibit good homogeneity about huge volumes and have a high destruction threshold, but are hygroscopic and possess a small nonlinearity.
A number of Attributes of the nonlinear crystal may be critical for an software e.g. in nonlinear frequency conversion:
In lots of situations, a nonlinear crystal utilized for nonlinear frequency conversion has a really long lifetime, which can be lengthier than that of The complete laser technique. The crystal material is basically not modified all through operation. Having said that, a diminished crystal life span can take place less than numerous situations:
GWU-Lasertechnik features all common nonlinear crystals like LBO, BBO and KTP using a wide assortment of specifications. Beside the nicely-recognized materials, impressive crystals like CLBO or BiBO with excellent Houses for e. g. deep-UV technology or large-ability ultrashort pulse lasers can be found. It does not matter if person items for R & D functions are essential or Price tag-efficient numbers in tiny, medium click here or massive batches with in-time shipping for that output line are desired: GWU’s focused service really helps to locate the ideal core elements for the application.
Optical crystals can show distinct sorts of optical nonlinearities, which may be utilized in different means:
Significant Destruction Threshold: BIBO crystal has a high damage threshold, permitting it to withstand high laser ability without the need of suffering destruction. This attribute helps make BIBO suitable for use in high-electrical power laser systems.
