BIBO crystal (bismuth triborate) is a relatively novel nonlinear substance compared with BBO and LBO crystals. BIBO crystal surpasses BBO when it comes to its successful nonlinearity, although also supplying a broader bandgap in comparison to KTP crystal.
If the crystal surfaces are still “dirty�?just after the above mentioned cleaning methods, the surfaces may need been ruined. Remember to Speak to us for rework on the crystals.

The quantity of the solvent may be altered for a variety of crystal dimension And so the lens tissue is kept moist for the entire drag but there is not any obvious trace of solvent around the crystal floor after the drag is completed. Inspect the area and repeat if required, but only use each sheet of lens tissue after.
BIBO crystals can be used as high-performance frequency doubling and frequency summing equipment and have wide software prospects in optical parametric oscillation (OPO).
Even though the crystal materials or coating isn't sensitive to h2o, smaller drinking water droplets could focus laser radiation additional tightly than under normal Procedure, and thus harm the crystal product.
At present, as a kind of wonderful nonlinear 2nd harmonic crystal, it can be utilized to provide superior effectiveness crystal of environmentally friendly or blue laser.
Bismuth Triborate (BiB3O6 or BIBO) is usually a recently created nonlinear optical crystal. It possesses large helpful nonlinear coefficient, substantial hurt threshold and inertness with regard to dampness.
Even though the nonlinear coefficient of KTP crystal is significant, the laser hurt threshold is low, that may trigger challenges for example refractive index change and transmission loss. BIBO crystal has increased laser destruction threshold and higher second harmonic conversion effectiveness. Although LBO and B-BBO are one of the most simple, They're tiny in size and have specific hygroscopicity, even though BIBO crystals are non-damp and may increase to significant sizing. These advantages help BIBO crystals to be greatly made use of.
Crystals which happen to be non-critically section-matched inside of a crystal oven may perhaps show challenges if the crystal temperature is transformed also swiftly or much too generally. Specifically, anti-reflection coatings could be broken due to distinctive thermal expansion coefficients with the concerned elements.
In lots of cases, a nonlinear crystal employed for nonlinear frequency conversion has an extremely extended life span, that's longer than that of The full laser system. The crystal product is essentially not click here modified during operation. Having said that, a lowered crystal life time can arise underneath many situations:
The load on the solvent will induce the lens tissue to return into connection with the crystal area. Gradually but steadily drag the moist lens tissue over the crystal floor remaining very careful never to elevate the lens tissue off of the surface area. Proceed dragging the lens tissue right up until it truly is off in the surface.
The Coating curves, transmittance curves, flatness reviews and surface area good quality report underneath microscope for BiBO Crystal are going to be provided when transported.
Considering that the second harmonic (SHG) might be widely accustomed to generate coherent seen light-weight and ultraviolet radiation, folks listen to it, but the traditional nonlinear crystals for example KDP, LBO, KTP, B-BBO even have several shortcomings. BIBO crystal is a different kind of nonlinear crystal. When compared with KDP crystal, it will make up for your drawback that KDP crystal can increase in significant size but dissolve in h2o.
