BIBO crystal (bismuth triborate) is a relatively novel nonlinear content in comparison with BBO and LBO crystals. BIBO crystal surpasses BBO in terms of its productive nonlinearity, although also presenting a broader bandgap compared to KTP crystal.
If the crystal surfaces are still “soiled�?immediately after the above cleansing techniques, the surfaces might have been destroyed. Please Make contact with us for rework on the crystals.
five mm to minimize group velocity mismatch and are ideal for frequency doubling or tripling of Ti:sapphire and Yb:doped laser pulses. The essential and noncritical period matching LBO crystals are ideal for next or third harmonic generation of Nd:YAG and Yb:doped lasers.
Crystal lifetime can be strongly depending on the fabric good quality, Though selected degradation phenomena appear to be intrinsic restrictions of the material.
Also, it could be remarkably desirable to utilize a crystal product that may be critically phase-matched at room temperature since noncritical phase matching usually entails the operation of your crystal inside of a temperature-stabilized crystal oven. However, the feasibility of significant period matching could be offered just for sufficiently high peak powers.
Making use of our promotion deal, you could Screen your symbol, additional below your item description, and these will been noticed by lots of photonics experts.
Notice that whether or not the nominal intensity is down below the nominal damage threshold, there may be troubles resulting from fluctuations during the beam electric power or community intensity (e.g., if a beam profile has “hot places�?, or due to isolated defects within a crystal, that happen to be more delicate compared to the frequent crystal substance.
Bismuth Triborate (BiB3O6 or BIBO) is actually a recently developed nonlinear optical crystal. It possesses huge helpful nonlinear coefficient, substantial destruction threshold click here and inertness with respect to humidity.
Even though the nonlinear coefficient of KTP crystal is massive, the laser destruction threshold is very low, that will bring about challenges such as refractive index modify and transmission loss. BIBO crystal has greater laser hurt threshold and better second harmonic conversion efficiency. Whilst LBO and B-BBO are the most useful, They're little in size and possess specified hygroscopicity, though BIBO crystals are non-wet and might expand to huge dimension. These rewards enable BIBO crystals to get commonly made use of.
Many alternative Qualities of a nonlinear crystal might be vital for an software e.g. in nonlinear frequency conversion:
Non-linear Optical (NLO) crystals present an enormously adaptable Option for generating new wavelengths from present, off-the-shelf laser sources. The optical wavelength spectrum is utilized by a considerable and continually expanding assortment of apps, from production of clinical lasers, quantum networking & computing via to environmental sensing and also quite a few others.
China BIBO crystals may be used not just as significant-efficiency frequency doubling and frequency summing units, but even have broad software prospective customers in the sector of optical parametric oscillation (OPO), and In addition it has an important software while in the effective technology of ultrabright entangled photons by means of blue pumped Spontaneous Parametric Down Conversions (Also Know as SPDC).
Optical crystals can show unique kinds of optical nonlinearities, that may be used in numerous means:
Significant Destruction Threshold: BIBO crystal has a large hurt threshold, making it possible for it to resist significant laser electric power without suffering injury. This attribute would make BIBO appropriate for use in high-power laser programs.
