The susceptibility to moisture of BiBO is extremely low. On the other hand, consumers are advised to deliver dry circumstances for both of those use and storage of BiBO to prolong the life span. Water condensation on crystal surfaces ought to be absolutely averted Anytime.
Inertness to Dampness: BIBO crystal is inert to moisture, meaning it does not degrade or eliminate its optical Homes when subjected to humidity. This would make BIBO a far more stable and trusted option for optical purposes in different environments.
5 mm to reduce group velocity mismatch and are perfect for frequency doubling or tripling of Ti:sapphire and Yb:doped laser pulses. The crucial and noncritical period matching LBO crystals are ideal for 2nd or 3rd harmonic technology of Nd:YAG and Yb:doped lasers.

Lithium niobate (LiNbO3) and lithium tantalate (LiTaO3) are materials with a relatively sturdy nonlinearity. They in many cases are utilized for nonlinear frequency conversion and also for electro-optic modulators. The two elements are available in congruent and in stoichiometric form, with essential variations concerning periodic poling and photorefractive results (see beneath). Lithium niobate and tantalate would be the most often made use of elements within the context of periodic poling; the resulting products are termed PPLN (periodically poled lithium niobate) and PPLT, respectively, or PPSLN and PPSLT for your stoichiometric versions.
Bismuth Triborate (BiB3O6 or BIBO) is really a recently designed nonlinear optical crystal. It possesses massive powerful nonlinear coefficient, substantial hurt threshold and inertness with respect to humidity.
Even though the nonlinear coefficient of KTP crystal is massive, the laser harm threshold is very low, which can induce difficulties for instance refractive index alter and transmission reduction. BIBO crystal has higher laser problems threshold and better second harmonic conversion efficiency. Despite the fact that LBO and B-BBO are probably the most functional, they are compact in dimension and have specific hygroscopicity, when BIBO crystals are non-soaked and will mature to significant dimensions. These pros enable BIBO crystals to be greatly made use of.
Borates for example LBO and BBO also do the job effectively in broadly tunable optical parametric oscillators and optical parametric chirped-pulse amplification.
) 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 away dust particles. Blow from the floor gently. Don't blow from the crystal itself from a hand!
China BIBO crystals can be used not simply as substantial-efficiency frequency doubling and frequency summing equipment, but also have wide application potential customers in the sphere of optical parametric oscillation (OPO), and In addition it has a vital application from the effective technology of ultrabright entangled photons by means of blue pumped Spontaneous Parametric Down Conversions (Also Know as SPDC).
Substantial electric power laser program: BIBO crystals are ideal for use in significant-electrical power laser techniques because of their superior injury threshold and their skill to withstand significant-intensity laser beams devoid of injury. This offers BIBO crystals a major gain in laser applications here that call for high Electricity output.
Significant Harm Threshold: BIBO crystal features a higher harm threshold, enabling it to withstand higher laser power without struggling hurt. This characteristic makes BIBO well suited for use in significant-electricity laser methods.
