BIBO crystal (bismuth triborate) is a comparatively novel nonlinear content when put next with BBO and LBO crystals. BIBO crystal surpasses BBO with regard to its productive nonlinearity, although also giving a broader bandgap in comparison to KTP crystal.
Laser processing and substance managing: In the field of laser processing and materials dealing with, the higher electrical power ability of BIBO crystals makes them a important part during the manufacture of high Vitality density laser beams.
five mm to minimize team velocity mismatch and are ideal for frequency doubling or tripling of Ti:sapphire and Yb:doped laser pulses. The critical and noncritical stage matching LBO crystals are ideal for 2nd or 3rd harmonic generation of Nd:YAG and Yb:doped lasers.
With a large powerful nonlinear coefficient, significant damage threshold, and inertness to dampness, BIBO crystal offers quite a few rewards more than other nonlinear optical materials for instance LBO and BBO.
BIBO crystals can be utilized as substantial-effectiveness frequency doubling and frequency summing equipment and possess broad software prospective buyers in optical parametric oscillation (OPO).
GWU-Lasertechnik has in excess of 30 a long time of practical experience in distributing laser crystals. Pick out GWU to reap the benefits of our vast information and in-discipline expertise!
At this time, as a kind of fantastic nonlinear next harmonic crystal, it may be used to generate large performance crystal of inexperienced or blue laser.
Operation of nonlinear crystals at temperatures below place temperature (to obtain phase matching) is normally problematic, as it might result in condensation of water within the crystal surfaces When the surrounding air just isn't very dry.
Although the nonlinear coefficient website of KTP crystal is massive, the laser injury threshold is small, which can result in issues for example refractive index modify and transmission reduction. BIBO crystal has larger laser problems threshold and higher second harmonic conversion effectiveness. Even though LBO and B-BBO are by far the most simple, They're small in size and also have certain hygroscopicity, even though BIBO crystals are non-moist and might develop to big size. These rewards empower BIBO crystals to be commonly utilized.
A variety of Qualities of a nonlinear crystal may be crucial for an software e.g. in nonlinear frequency conversion:
) to blow off dust together with other loose contaminants very first. If a dry nitrogen line is obtainable within the lab, an air gun can be applied to blow absent dust particles. Blow from the surface Carefully. Do not blow from the crystal itself from your hand!
芯飞睿所有的服务和支持都立足于使我们的客人工作的更加高效，更有价值。
The Coating curves, transmittance curves, flatness reports and floor high quality report less than microscope for BiBO Crystal is going to be provided when delivered.
Large Destruction Threshold: BIBO crystal has a substantial hurt threshold, making it possible for it to withstand high laser ability devoid of suffering harm. This attribute can make BIBO ideal for use in high-electric power laser techniques.
