A Simple Key For BIBO Crystal Unveiled

If you do not locate the suitable solutions above, it's possible you'll let's know your requirements or applications in the form underneath. Our sales or technical staff will get back to you as soon as possible.

Laser processing and substance handling: In the field of laser processing and content dealing with, the significant ability capability of BIBO crystals tends to make them a crucial component while in the manufacture of large Vitality density laser beams.

5 mm to attenuate team velocity mismatch and are ideal for frequency doubling or tripling of Ti:sapphire and Yb:doped laser pulses. The vital and noncritical phase matching LBO crystals are perfect for next or third harmonic generation of Nd:YAG and Yb:doped lasers.

Typically, the crystal materials should have a substantial optical transparency for all wavelengths involved �?for instance, for pump, sign and idler in an optical parametric amplifier.

Both have a relatively lower destruction threshold, but usually do not need to be operated at high intensities because of their high nonlinearity. They've got a bent for photorefractive effects, which are detrimental for frequency conversion, but are utilized for, e.g., holographic facts storage in Fe-doped LiNbO3 crystals. The tendency for “photorefractive harm�?relies upon strongly on the material composition; e.g. it might be reduced through MgO doping and by using a stoichiometric composition.

Lithium niobate (LiNbO3) and lithium tantalate (LiTaO3) are resources with a comparatively strong nonlinearity. They are often useful for nonlinear frequency conversion and also for electro-optic modulators. The two supplies can be found in congruent and in stoichiometric kind, with important variations relating to periodic poling and photorefractive effects (see down below). Lithium niobate and tantalate are the most frequently more info utilised elements while in the context of periodic poling; the resulting components are named PPLN (periodically poled lithium niobate) and PPLT, respectively, or PPSLN and PPSLT for your stoichiometric versions.

And is particularly advantageous for building wavelengths during the eco-friendly and blue spectrum by constant-wave (CW) radiation. The elevated effective nonlinearity of BIBO crystal not simply improves the performance of your SHG approach but also facilitates the utilization of shorter crystal lengths—an indispensable attribute when endeavoring to engineer compact laser systems.

They exhibit great homogeneity above substantial volumes and have a large hurt threshold, but are hygroscopic and have a low nonlinearity.

the chemical durability; e.g., some crystal supplies are hygroscopic, Some others go through chemical improvements when heated inside of a vacuum chamber for software of the dielectric coating

  )  to blow off dust together with other unfastened contaminants to start with. If a dry nitrogen line is accessible inside the lab, an air gun will also be used  to blow absent dust particles. Blow off the floor Carefully. Will not blow from the crystal by itself from the hand!

This mix makes BIBO crystal exceptionally suited to harnessing the phenomenon of 2nd harmonic era (SHG) within just solid-state lasers and laser diodes.

linear absorption, which may cause heating at higher optical electrical power amounts, so that the phase matching is disturbed, and thermal lensing may perhaps arise

Since the next harmonic (SHG) could be commonly used to generate coherent visible mild and ultraviolet radiation, persons listen to it, but the traditional nonlinear crystals for example KDP, LBO, KTP, B-BBO also have a lot of shortcomings. BIBO crystal is a new variety of nonlinear crystal. In contrast with KDP crystal, it helps make up for that downside that KDP crystal can grow in huge dimensions but dissolve in drinking water.
