Inertness to Moisture: BIBO crystal is inert to moisture, which means it doesn't degrade or get rid of its optical Houses when subjected to humidity. This makes BIBO a far more secure and dependable selection for optical programs in a variety of environments.
Laser processing and product dealing with: In the field of laser processing and product dealing with, the high electric power capacity of BIBO crystals will make them a essential ingredient inside the manufacture of significant Electrical power density laser beams.
five mm to reduce group velocity mismatch and are perfect for frequency doubling or tripling of Ti:sapphire and Yb:doped laser pulses. The essential and noncritical phase matching LBO crystals are perfect for second or 3rd harmonic generation of Nd:YAG and Yb:doped lasers.
Typically, the crystal content must have a substantial optical transparency for all wavelengths included �?one example is, for pump, sign and idler in an optical parametric amplifier.
Each have a comparatively lower damage threshold, but tend not to should be operated at large intensities because of their higher nonlinearity. They have got a tendency for photorefractive results, which happen to be detrimental for frequency conversion, but are utilized for, e.g., holographic details storage in Fe-doped LiNbO3 crystals. The inclination for “photorefractive injury�?is dependent strongly on the fabric composition; e.g. it might be lowered by means of MgO doping and by making use of a stoichiometric composition.
Dust and stains on crystal surfaces could potentially cause scattering/reduction of light and may even react with gentle to damage check here optical surfaces in a higher incident laser ability.
Be aware that even when the nominal depth is underneath the nominal hurt threshold, there may be problems as a consequence of fluctuations from the beam electric power or local depth (e.g., if a beam profile has “scorching spots�?, or because of isolated defects in a very crystal, that happen to be additional sensitive compared to standard crystal content.
Operation of nonlinear crystals at temperatures down below room temperature (to attain section matching) is usually problematic, as it could lead to condensation of h2o around the crystal surfaces When the surrounding air just isn't pretty dry.
In summary, BIBO crystal is usually a promising nonlinear optical material with Outstanding Homes which make it suitable for a wide array of optical applications.
Crystals which are non-critically period-matched inside a crystal oven may perhaps show troubles when the crystal temperature is adjusted also fast or much too typically. In particular, anti-reflection coatings could possibly be broken resulting from various thermal enlargement coefficients of your concerned elements.
Even nicely under the edge for instant injury, some crystal elements show a steady degradation throughout the utilized volume, e.
This mixture helps make BIBO crystal exceptionally fitted to harnessing the phenomenon of next harmonic era (SHG) inside strong-point out lasers and laser diodes.
The Coating curves, transmittance curves, flatness stories and surface excellent report below microscope for BiBO Crystal are going to be presented when shipped.
Considering that the 2nd harmonic (SHG) might be broadly used to produce coherent seen mild and ultraviolet radiation, persons pay attention to it, but the traditional nonlinear crystals including KDP, LBO, KTP, B-BBO also have several shortcomings. BIBO crystal is a new form of nonlinear crystal. As opposed with KDP crystal, it makes up for the disadvantage that KDP crystal can expand in substantial measurement but dissolve in water.
