The susceptibility to humidity of BiBO is rather low. Nevertheless, buyers are encouraged to provide dry circumstances for both equally use and storage of BiBO to extend the life span. Water condensation on crystal surfaces need to be Definitely averted at any time.
Inertness to Dampness: BIBO crystal is inert to moisture, which means it doesn't degrade or eliminate its optical Homes when subjected to humidity. This can make BIBO a more stable and trusted choice for optical purposes in a variety of environments.
Inspect the crystal surface area for dust and stains by Keeping it in close proximity to a brilliant obvious-gentle source. Viewing at distinct angles might help see scattering from dust and stains. The crystal area must be cleaned as explained beneath if dust and stains are uncovered.
The level of the solvent might be adjusted for several crystal measurement so the lens tissue is retained damp for the whole drag but there is not any obvious trace of solvent within the crystal floor after the drag is concluded. Inspect the surface and repeat if important, but only use Each and every sheet of lens tissue at the time.
BIBO crystals can be used as substantial-performance frequency doubling and frequency summing devices and have broad application prospective buyers in optical parametric oscillation (OPO).
Regardless of whether the crystal materials or coating will not be delicate to water, small water droplets may well concentrate laser radiation much more tightly than less than usual operation, and thus problems the crystal content.
Notice that regardless of whether the nominal depth is below the nominal problems threshold, there might be problems on account of fluctuations during the beam energy or nearby intensity (e.g., if a beam profile has “scorching spots�?, or because of isolated defects inside a crystal, which can be a lot more sensitive than the frequent crystal product.
Scientific study and development: BIBO crystals also Participate in a very important job in scientific exploration and advancement. Its superb nonlinear optical performance supplies new resources and options for ultrafast phenomenon study, potent area physics, biomedical imaging and other fields
Although the nonlinear coefficient of KTP crystal is huge, the laser damage threshold is reduced, that may result in challenges like refractive index transform and transmission decline. BIBO crystal has larger laser problems threshold and better second harmonic conversion efficiency. Despite the fact that LBO and B-BBO are the most useful, These are compact in size and have certain hygroscopicity, while BIBO crystals are non-wet and can grow to large size. These positive aspects permit BIBO crystals for being extensively utilized.
Extreme optical intensities in the course of Procedure may possibly instantaneously damage a crystal. Regrettably, nonlinear crystals frequently should be operated not much from their optical destruction threshold to attain a sufficiently significant conversion efficiency. This implies a trade-off involving conversion efficiency and crystal lifetime.
) to blow off dust together with other free contaminants very first. If a dry nitrogen line is obtainable within the lab, an air gun can also be made use of to blow absent dust particles. Blow off the area gently. Do not blow from the crystal itself from the hand!

Optical crystals can show various styles of BIBO Crystal optical nonlinearities, which may be used in different ways:
flux-developed KTP and RTP with its higher nonlinearity, also in variants with substantial gray tracking resistance
