BIBO crystal (bismuth triborate) is a relatively novel nonlinear material when put next with BBO and LBO crystals. BIBO crystal surpasses BBO concerning its efficient nonlinearity, even though also giving a broader bandgap compared to KTP crystal.
Inertness to Moisture: BIBO crystal is inert to moisture, which means it doesn't degrade or shed its optical properties when exposed to humidity. This helps make BIBO a far more secure and trustworthy option for optical applications in different environments.
Almost all of the standard nonlinear crystals like BBO, LBO, BiBO or KTP for frequency doubling, tripling and quadrupling of the elemental laser radiation can be found from stock. Customer-precise dimensions and AR coatings also are presented at competitive costs.
Typically, the crystal material must have a high optical transparency for all wavelengths concerned �?such as, for pump, sign and idler in an optical parametric amplifier.

Dust and stains on crystal surfaces can result in scattering/reduction of light and can even react with light to wreck optical surfaces in a significant incident laser electric power.
Filters underneath or the shape at the bottom can be used to aid products lookup or make more inquiries.
And is particularly beneficial for generating wavelengths inside the inexperienced and blue spectrum via constant-wave (CW) radiation. The elevated successful nonlinearity of BIBO crystal not only boosts the efficiency of your SHG method and also facilitates the utilization of shorter crystal lengths—an indispensable attribute when endeavoring to engineer compact laser methods.
Although the nonlinear coefficient of KTP crystal is significant, the laser problems threshold is very low, that can trigger problems which include refractive index adjust and transmission decline. BIBO crystal has larger laser damage threshold and higher 2nd harmonic conversion performance. Although LBO and B-BBO are quite possibly the most simple, They can be small in measurement and possess BIBO Crystal certain hygroscopicity, though BIBO crystals are non-wet and might expand to large size. These rewards allow BIBO crystals being broadly made use of.
Borates for example LBO and BBO also get the job done nicely in broadly tunable optical parametric oscillators and optical parametric chirped-pulse amplification.
Non-linear Optical (NLO) crystals supply an enormously versatile Option for generating new wavelengths from existing, off-the-shelf laser resources. The optical wavelength spectrum is used by a large and regularly increasing range of programs, from production of clinical lasers, quantum networking & computing by way of to environmental sensing together with lots of others.
This mixture will make BIBO crystal extremely suited to harnessing the phenomenon of 2nd harmonic technology (SHG) in just reliable-condition lasers and laser diodes.
linear absorption, that may lead to heating at substantial optical electricity ranges, so the section matching is disturbed, and thermal lensing may arise
