BIBO crystal (bismuth triborate) is a relatively novel nonlinear content compared with BBO and LBO crystals. BIBO crystal surpasses BBO when it comes to its powerful nonlinearity, when also offering a broader bandgap in comparison to KTP crystal.
Laser processing and material handling: In the sector of laser processing and materials handling, the higher energy capability of BIBO crystals tends to make them a important element from the manufacture of high energy density laser beams.
five mm to minimize team velocity mismatch and are ideal for frequency doubling or tripling of Ti:sapphire and Yb:doped laser pulses. The important and noncritical phase matching LBO crystals are perfect for 2nd or third harmonic technology of Nd:YAG and Yb:doped lasers.
Crystal lifetime can be strongly depending on the fabric high quality, While sure degradation phenomena appear to be intrinsic limitations of the material.
Both equally have a comparatively minimal injury threshold, but do not must be operated at substantial intensities due to their superior nonlinearity. They've got an inclination for photorefractive results, that are harmful for frequency conversion, but are useful for, e.g., holographic facts storage in Fe-doped LiNbO3 crystals. The tendency for “photorefractive damage�?relies upon strongly on the fabric composition; e.g. it may be reduced via MgO doping and by making use of a stoichiometric composition.

Bismuth Triborate (BiB3O6 or BIBO) is actually a newly made nonlinear optical crystal. It possesses massive efficient nonlinear coefficient, superior destruction threshold and inertness with respect to humidity.
Although the nonlinear coefficient of KTP crystal is huge, the laser problems threshold is small, that will bring about problems including refractive index adjust and transmission reduction. BIBO crystal has increased laser destruction threshold and better 2nd harmonic conversion effectiveness. Despite the fact that LBO and B-BBO are quite possibly the most practical, they are compact in measurement and have sure hygroscopicity, when BIBO crystals are non-damp and might mature to significant dimensions. These pros help BIBO crystals to become extensively employed.
Borates like LBO and BBO also operate very well in broadly tunable optical parametric oscillators and more info optical parametric chirped-pulse amplification.
) to blow off dust along with other loose contaminants initial. If a dry nitrogen line is accessible in the lab, an air gun will also be used to blow absent dust particles. Blow off the area gently. Do not blow from the crystal itself from the hand!

Substantial electrical power laser program: BIBO crystals are ideal for use in high-ability laser devices due to their high destruction threshold and their capability to face up to large-intensity laser beams devoid of injury. This offers BIBO crystals a major advantage in laser apps that demand superior Vitality output.
