If you don't find the suited solutions previously mentioned, you might allow us to know your prerequisites or programs in the form under. Our product sales or technical workers can get back again for you as quickly as possible.
Inertness to Humidity: BIBO crystal is inert to moisture, meaning it doesn't degrade or eliminate its optical Houses when exposed to humidity. This makes BIBO a far more stable and responsible choice for optical apps in numerous environments.
5 mm to attenuate team velocity mismatch and are perfect for frequency doubling or tripling of Ti:sapphire and Yb:doped laser pulses. The vital and noncritical section matching LBO crystals are ideal for next or 3rd harmonic generation of Nd:YAG and Yb:doped lasers.
The level of the solvent could be adjusted for various crystal dimensions Therefore the lens tissue is kept damp for the whole drag but there is not any noticeable trace of solvent over the crystal floor after the drag is completed. Inspect the area and repeat if important, but only use Each and every sheet of lens tissue at the time.
Both of those have a relatively small destruction threshold, but do not need to be operated at large intensities due to their large nonlinearity. They've got a bent for photorefractive results, that happen to be detrimental for frequency conversion, but are used for, e.g., holographic data storage in Fe-doped LiNbO3 crystals. The inclination for “photorefractive problems�?is dependent strongly on the material composition; e.g. it might be lessened by using MgO doping and through the use of a stoichiometric composition.
Make sure you use "Increase to Cart" to place the attention-grabbing items during the purchasing cart. Take a look at with on the web payment or ask us for the prices/availability through the procuring cart.
Lithium niobate (LiNbO3) and lithium tantalate (LiTaO3) are products with a comparatively robust nonlinearity. They are frequently used click here for nonlinear frequency conversion in addition to for electro-optic modulators. Equally supplies can be found in congruent and in stoichiometric variety, with critical variations about periodic poling and photorefractive results (see underneath). Lithium niobate and tantalate tend to be the most often applied supplies from the context of periodic poling; the ensuing supplies are identified as PPLN (periodically poled lithium niobate) and PPLT, respectively, or PPSLN and PPSLT for the stoichiometric versions.
And is especially beneficial 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 simply enhances the efficiency on the SHG process but in addition facilitates the utilization of shorter crystal lengths—an indispensable attribute when endeavoring to engineer compact laser units.
In summary, BIBO crystal is usually a promising nonlinear optical materials with Excellent Homes which make it suited to an array of optical programs.
the chemical durability; e.g., some crystal resources are hygroscopic, others go through chemical variations when heated inside a vacuum chamber for application of the dielectric coating
Even perfectly down below the brink for instant destruction, some crystal supplies exhibit a continual degradation in the utilized quantity, e.
GWU-Lasertechnik provides all typical nonlinear crystals like LBO, BBO and KTP having a wide a number of requirements. Beside the well-established elements, innovative crystals like CLBO or BiBO with outstanding properties for e. g. deep-UV generation or significant-electrical power ultrashort pulse lasers are offered. Regardless of if person items for R & D needs are needed or cost-efficient quantities in smaller, medium or significant batches with in-time shipping for your production line are needed: GWU’s dedicated company helps to discover the ideal core factors on your application.
The magnitude of the effective nonlinear coefficient depends on the nonlinear tensor components and within the used phase-matching configuration. A significant nonlinearity is essential especially Should the achievable optical intensities are reduced.
flux-developed KTP and RTP with its superior nonlinearity, also in variants with high grey monitoring resistance
