The susceptibility to dampness of BiBO is quite minimal. Nevertheless, users are encouraged to supply dry circumstances for both use and storage of BiBO to lengthen the lifetime. Water condensation on crystal surfaces really should be Definitely prevented Anytime.
Inertness to Moisture: BIBO crystal is inert to moisture, which suggests it doesn't degrade or drop its optical Qualities when exposed to humidity. This would make BIBO a more secure and reputable option for optical apps in numerous environments.
5 mm to attenuate team velocity mismatch and are ideal for frequency doubling or tripling of Ti:sapphire and Yb:doped laser pulses. The critical and noncritical stage matching LBO crystals are perfect for next or 3rd harmonic generation of Nd:YAG and Yb:doped lasers.
Ordinarily, the crystal content ought to have a substantial optical transparency for all wavelengths concerned �?by way of example, for pump, signal and idler in an optical parametric amplifier.
Also, it might be really attractive to make use of a crystal product which can be critically stage-matched at space temperature for the reason that noncritical period matching frequently requires the operation on the crystal in a very temperature-stabilized crystal oven. Having said that, the feasibility of critical phase matching could be provided only for adequately superior peak powers.
You should use "Include to Cart" to place the appealing products inside the procuring cart. Consider with on line payment or check with us for the costs/availability via the procuring cart.
Filters under or the form at the bottom may be used to assist solution research or make even more inquiries.
Procedure of nonlinear crystals at temperatures beneath place temperature (to accomplish stage matching) is normally problematic, as it might result in condensation of h2o to the crystal surfaces In the event the bordering air will not be extremely dry.
rystal surface is horizontal and marginally higher than your fingers. Have a fresh, clean up sheet of lens tissue and location it about the crystal. Make certain the lens tissue could be drawn across the crystal area. Up coming, place a little fall of pure isopropyl alcohol (IPA) over the lens tissue on top of the crystal surface.
Crystals that are non-critically section-matched in a crystal oven may possibly show issues if the crystal temperature is changed also speedily or as well often. In particular, anti-reflection coatings could be destroyed because of distinct thermal growth coefficients from the associated supplies.
Bismuth Triborate (BiB3O6 or BIBO) can be a recently developed nonlinear optical crystal. It possesses large successful nonlinear coefficient, higher injury threshold and inertness with respect to humidity.
China BIBO get more info crystals can be utilized not merely as significant-effectiveness frequency doubling and frequency summing equipment, but even have wide software potential customers in the sphere of optical parametric oscillation (OPO), and Additionally, it has an important application inside the productive technology of ultrabright entangled photons by way of blue pumped Spontaneous Parametric Down Conversions (Also Know as SPDC).
The magnitude on the successful nonlinear coefficient will depend on the nonlinear tensor parts and within the used phase-matching configuration. A substantial nonlinearity is very important particularly If your achievable optical intensities are reduced.
Considering that the next harmonic (SHG) might be broadly accustomed to make coherent obvious gentle and ultraviolet radiation, men and women pay attention to it, but the traditional nonlinear crystals for example KDP, LBO, KTP, B-BBO even have a lot of shortcomings. BIBO crystal is a brand new variety of nonlinear crystal. When compared with KDP crystal, it can make up for your downside that KDP crystal can expand in large measurement but dissolve in h2o.
