BIBO crystal (bismuth triborate) is a relatively novel nonlinear product in comparison with BBO and LBO crystals. BIBO crystal surpasses BBO concerning its efficient nonlinearity, though also providing a broader bandgap in comparison to KTP crystal.
Laser processing and substance dealing with: In the field of laser processing and content dealing with, the higher energy capability of BIBO crystals can make them a key part inside the manufacture of higher Electrical power density laser beams.
Inspect the crystal surface for dust and stains by holding it close to a brilliant visible-light-weight source. Viewing at unique angles may help see scattering from dust and stains. The crystal surface area should be cleaned as described under if dust and stains are found.
The level of the solvent can be modified for several crystal sizing so the lens tissue is saved moist for the whole drag but there's not any obvious trace of solvent within the crystal floor once the drag is finished. Inspect the floor and repeat if vital, but only use Each individual sheet of lens tissue the moment.
Also, it could be remarkably fascinating to employ a crystal material which may be critically stage-matched at room temperature for the reason that noncritical section matching generally will involve the operation of your crystal within a temperature-stabilized crystal oven. Nevertheless, the feasibility of essential phase matching may be presented just for sufficiently substantial peak powers.
GWU-Lasertechnik has much more than 30 years of experience in distributing laser crystals. Opt for GWU to take advantage of our wide awareness As well as in-discipline encounter!
The selection of the best suited crystal product for any supplied software is commonly much from trivial; it really should involve the thought of numerous facets. One example is, a significant nonlinearity for frequency conversion of ultrashort pulses will not aid If your conversation duration is strongly minimal by a substantial team velocity mismatch plus the very low destruction threshold boundaries the applicable optical intensities.
And is particularly advantageous for producing wavelengths in the environmentally friendly and blue spectrum by means of continuous-wave (CW) radiation. The elevated productive nonlinearity of BIBO crystal not only enhances the efficiency of your SHG procedure 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 big, the laser harm threshold is reduced, which will cause complications which include refractive index transform and transmission loss. BIBO crystal has higher laser problems threshold and higher next harmonic conversion efficiency. While LBO and B-BBO are one of the most sensible, they are modest in dimension and also have certain hygroscopicity, when BIBO crystals are non-wet and might develop to massive dimension. These rewards enable BIBO crystals to get widely utilised.
A variety of properties of the nonlinear crystal may be vital for an application e.g. in nonlinear frequency conversion:
Even well below the threshold for fast destruction, some crystal materials show a continual degradation throughout the made use of quantity, e.
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。
linear absorption, which can result in heating at significant optical power levels, so that the phase matching is disturbed, and thermal lensing might take place
Since the second harmonic (SHG) is often widely used to make coherent obvious light-weight and ultraviolet radiation, more info folks pay attention to it, but the standard nonlinear crystals including KDP, LBO, KTP, B-BBO also have numerous shortcomings. BIBO crystal is a whole new style of nonlinear crystal. As opposed with KDP crystal, it tends to make up to the disadvantage that KDP crystal can develop in big dimension but dissolve in water.
