The susceptibility to dampness of BiBO may be very very low. Nevertheless, buyers are encouraged to supply dry problems for equally use and storage of BiBO to lengthen the lifetime. Drinking water condensation on crystal surfaces need to be absolutely avoided Anytime.
If the crystal surfaces are still “soiled�?just after the above cleaning treatments, the surfaces might have been damaged. Be sure to Speak to us for rework of your crystals.
The majority of the conventional nonlinear crystals like BBO, LBO, BiBO or KTP for frequency doubling, tripling and quadrupling of the basic laser radiation can be found from inventory. Client-distinct dimensions and AR coatings are also made available at aggressive selling prices.
The amount of the solvent might be modified for a variety of crystal dimension And so the lens tissue is stored damp for the entire drag but there is not any seen trace of solvent to the crystal surface following the drag is completed. Inspect the surface and repeat if important, but only use Every single sheet of lens tissue once.
Both have a comparatively reduced damage threshold, but usually do not need to be operated at high intensities because of their high nonlinearity. They've an inclination for photorefractive results, which happen to be harmful for frequency conversion, but are useful for, e.g., holographic facts storage in Fe-doped LiNbO3 crystals. The tendency for “photorefractive harm�?is dependent strongly on the material composition; e.g. it can be decreased via MgO doping and by making use of a stoichiometric composition.
Make sure you use "Increase to Cart" to put the interesting goods during the buying cart. Have a look at with on line payment or check with us for the costs/availability by means of the searching cart.
The selection in the most suitable crystal product for just a presented more info application is commonly significantly from trivial; it really should entail the thought of many aspects. Such as, a high nonlinearity for frequency conversion of ultrashort pulses does not enable if the conversation size is strongly restricted by a considerable group velocity mismatch as well as lower harm threshold limitations the relevant optical intensities.
And is especially advantageous for generating wavelengths inside the green and blue spectrum by continuous-wave (CW) radiation. The elevated successful nonlinearity of BIBO crystal not simply improves the efficiency of your SHG process but in addition 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 substantial, the laser injury threshold is low, which is able to lead to difficulties like refractive index alter and transmission reduction. BIBO crystal has higher laser problems threshold and higher second harmonic conversion performance. Though LBO and B-BBO are essentially the most functional, They can be tiny in sizing and also have specific hygroscopicity, when BIBO crystals are non-damp and may mature to massive dimension. These advantages allow BIBO crystals to be widely made use of.
A number of Qualities of the nonlinear crystal might be critical for an software e.g. in nonlinear frequency conversion:
Even properly down below the edge for instant injury, some crystal resources show a constant degradation inside the utilized volume, e.
This combination would make BIBO crystal extremely suited for harnessing the phenomenon of next harmonic technology (SHG) in stable-point out lasers and laser diodes.
The magnitude on the productive nonlinear coefficient will depend on the nonlinear tensor parts and to the used section-matching configuration. A high nonlinearity is significant specifically When the achievable optical intensities are minimal.
flux-developed KTP and RTP with its high nonlinearity, also in variants with significant gray monitoring resistance
