The susceptibility to humidity of BiBO is rather lower. Even so, end users are suggested to deliver dry conditions for equally use and storage of BiBO to prolong the life span. H2o condensation on crystal surfaces must be Totally avoided Anytime.
If the crystal surfaces remain “soiled�?soon after the above cleansing treatments, the surfaces may have been harmed. You should Speak to us for rework on the crystals.
Most of the common nonlinear crystals like BBO, LBO, BiBO or KTP for frequency doubling, tripling and quadrupling of the fundamental laser radiation can be obtained from inventory. Client-certain Proportions and AR coatings will also be provided at competitive prices.
With a considerable effective nonlinear coefficient, substantial destruction threshold, and inertness to humidity, BIBO crystal presents quite a few benefits in excess of other nonlinear optical elements including LBO and BBO.
Equally have a relatively lower harm threshold, but will not need to be operated at substantial intensities because of their high nonlinearity. They've a bent for photorefractive consequences, that are detrimental for frequency conversion, but are employed for, e.g., holographic facts storage in Fe-doped LiNbO3 crystals. The tendency for “photorefractive injury�?is dependent strongly on the fabric composition; e.g. it may be diminished by means of MgO doping and by using a stoichiometric composition.
Even if the crystal product or coating is just not sensitive to h2o, modest water droplets may perhaps concentration laser radiation a lot more tightly than less than regular Procedure, and thus problems the crystal materials.
Be aware that even if the nominal intensity is down below the nominal problems threshold, there may be issues as a consequence of BIBO Crystal fluctuations while in the beam energy or community intensity (e.g., if a beam profile has “hot places�?, or on account of isolated defects inside a crystal, which can be more delicate as opposed to typical crystal product.
Procedure of nonlinear crystals at temperatures underneath area temperature (to obtain period matching) is generally problematic, as it may well bring on condensation of drinking water around the crystal surfaces Should the encompassing air just isn't very dry.
In the situation of ultrashort pulses the significant team velocity mismatch enforces the usage of a shorter crystal, which necessitates substantial optical intensities for just a offered conversion efficiency.
Excessive optical intensities through Procedure may possibly instantaneously destruction a crystal. Unfortunately, nonlinear crystals frequently have to be operated not significantly from their optical hurt threshold to attain a adequately large conversion effectiveness. This suggests a trade-off concerning conversion efficiency and crystal life time.
Non-linear Optical (NLO) crystals supply an enormously versatile Option for building new wavelengths from present, off-the-shelf laser resources. The optical wavelength spectrum is used by a large and continually expanding number of programs, from producing of healthcare lasers, quantum networking & computing via to environmental sensing along with several Other folks.
This combination will make BIBO crystal extremely suited to harnessing the phenomenon of second harmonic technology (SHG) in sound-state lasers and laser diodes.
Optical crystals can show diverse sorts of optical nonlinearities, that may be used in numerous ways:
Our crystals are Utilized in an array of applications, including numerous kinds of nonlinear frequency conversion and electro-optics, but also quantum technologies.
