If you do not find the acceptable solutions over, you might allow us to know your prerequisites or applications in the shape down below. Our revenue or technical staff will get back again to you as quickly as possible.
Inertness to Dampness: BIBO crystal is inert to moisture, which implies it does not degrade or shed its optical Homes when subjected to humidity. This makes BIBO a more secure and trusted option for optical purposes in a variety of environments.
Many of the standard nonlinear crystals like BBO, LBO, BiBO or KTP for frequency doubling, tripling and quadrupling of the basic laser radiation can be obtained from inventory. Customer-particular dimensions and AR coatings can also be supplied at competitive charges.
Generally, the crystal product should have a large optical transparency for all wavelengths involved �?one example is, for pump, sign and idler within an optical parametric amplifier.
Both equally have a comparatively small harm threshold, but usually do not have to be operated at substantial intensities due to their higher nonlinearity. They've got a bent for photorefractive results, that happen to be detrimental for frequency conversion, but are utilized for, e.g., holographic information storage in Fe-doped LiNbO3 crystals. The inclination for “photorefractive injury�?is dependent strongly on the material composition; e.g. it might be minimized via MgO doping and by making use of a stoichiometric composition.
Utilizing our promoting deal, you can Show your symbol, further below your item description, and these will been witnessed by quite a few photonics industry experts.
Note that whether or not the nominal depth is down below the nominal hurt threshold, there may be complications as a consequence of fluctuations from the beam power or nearby intensity (e.g., if a beam profile has “scorching places�?, or because of isolated defects in the crystal, which are more sensitive compared to the common crystal substance.
Bismuth Triborate (BiB3O6 or BIBO) is really a newly formulated nonlinear optical crystal. It possesses significant helpful nonlinear coefficient, significant problems threshold and inertness with respect to moisture.
Although the nonlinear coefficient of KTP crystal is big, the laser problems threshold is reduced, which is able to lead to complications including refractive index improve and transmission loss. BIBO crystal has larger laser problems threshold and better second harmonic conversion efficiency. Although LBO and B-BBO are one of the most simple, They're tiny in measurement and also have selected hygroscopicity, though BIBO crystals are non-wet and can grow to big size. These benefits enable BIBO crystals to become widely used.
Borates for example LBO and BBO also work effectively in broadly tunable optical parametric oscillators and optical parametric chirped-pulse amplification.
In several circumstances, a nonlinear crystal used for nonlinear frequency conversion has an exceptionally extended life span, which can be longer than that of The complete laser program. The crystal substance is essentially not modified for the duration of Procedure. Nevertheless, a diminished crystal life span can occur below numerous instances:
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。
Substantial electricity laser program: BIBO crystals are ideal for use in high-ability laser devices due to their higher destruction threshold as well as their capacity to withstand significant-intensity laser beams without problems. This gives BIBO crystals a major advantage in laser apps that need here superior Vitality output.
Considering the fact that the next harmonic (SHG) can be broadly utilized to make coherent noticeable gentle and ultraviolet radiation, individuals concentrate to it, but the traditional nonlinear crystals for example KDP, LBO, KTP, B-BBO even have quite a few shortcomings. BIBO crystal is a completely new form of nonlinear crystal. Compared with KDP crystal, it tends to make up to the downside that KDP crystal can grow in big dimensions but dissolve in h2o.
