5 Simple Techniques For BIBO Crystal
Blog Article
Hygroscopic crystal materials deteriorate when they're not often kept in adequately dry air (or possibly a dry purge gas). This applies e.g. to KDP and BBO, and in a lesser extent to LBO. It could be valuable to keep this type of crystal at a rather elevated temperature, which makes it simpler to maintain it dry.
If the crystal surfaces are still “filthy�?immediately after the above mentioned cleaning treatments, the surfaces might have been damaged. Please Get hold of us for rework from the crystals.
Many of the standard nonlinear crystals like BBO, LBO, BiBO or KTP for frequency doubling, tripling and quadrupling of the basic laser radiation are available from inventory. Customer-precise dimensions and AR coatings may also be offered at aggressive prices.
Crystal life time can be strongly dependent on the material top quality, Though specified degradation phenomena seem like intrinsic limits of the material.
Also, it might be hugely appealing to use a crystal substance that may be critically stage-matched at room temperature mainly because noncritical stage matching often includes the operation on the crystal inside a temperature-stabilized crystal oven. Even so, the feasibility of vital period matching could be given just for adequately substantial peak powers.
GWU-Lasertechnik has much more than thirty a long time of experience in distributing laser crystals. Opt for GWU to gain from our wide expertise As well as in-discipline experience!
Filters underneath or the shape at The underside can be employed to help merchandise lookup or make even more inquiries.
And is particularly advantageous for building wavelengths while in the green and blue spectrum by means of continual-wave (CW) radiation. The elevated successful nonlinearity of BIBO crystal not just boosts the effectiveness on the SHG method and also facilitates the utilization of shorter crystal lengths—an indispensable attribute when endeavoring to engineer compact laser devices.
They exhibit superior homogeneity above large volumes and also read more have a high hurt threshold, but are hygroscopic and have a minimal nonlinearity.
Extreme optical intensities for the duration of operation might immediately harm a crystal. Sadly, nonlinear crystals often should be operated not far from their optical damage threshold to achieve a adequately substantial conversion effectiveness. This suggests a trade-off concerning conversion effectiveness and crystal life span.
) to blow off dust and other loose contaminants first. If a dry nitrogen line is accessible within the lab, an air gun can also be employed to blow away dust particles. Blow off the surface gently. Will not blow from the crystal itself out of your hand!
This mixture would make BIBO crystal extremely suited for harnessing the phenomenon of second harmonic generation (SHG) within just strong-state lasers and laser diodes.
Optical crystals can show diverse kinds of optical nonlinearities, that may be used in various means:
g. in the shape of “gray monitoring�? Such phenomena are significantly common for Procedure with ultraviolet light-weight. Observe that a gradual degradation could also direct into quick catastrophic damage through extreme heat era.
