The susceptibility to humidity of BiBO may be very minimal. However, customers are encouraged to provide dry problems for equally use and storage of BiBO to prolong the lifetime. Water condensation on crystal surfaces needs to be Certainly avoided at any time.
If the crystal surfaces are still “dirty�?right after the above cleansing techniques, the surfaces might have been destroyed. Make sure you Call us for rework on the crystals.

Crystal life span will also be strongly depending on the material high quality, Though sure degradation phenomena appear to be intrinsic limitations of the fabric.
BIBO crystals may be used as significant-efficiency frequency doubling and frequency summing gadgets and also have wide software prospects in optical parametric oscillation (OPO).
Dust and stains on crystal surfaces might cause scattering/loss of light and can even react with gentle to damage optical surfaces at a superior incident laser ability.
Note that whether or not the nominal depth is beneath the nominal harm threshold, there might be issues due to fluctuations during the beam electrical power or community intensity (e.g., if a beam profile has “sizzling spots�?, or as a consequence of isolated defects in a very crystal, which are a lot more sensitive compared to the regular crystal content.
Crylink is really an open platform, equally as our mission is to attach price, Crylink believes that each man or woman and each business has unique value, and we hope to connect with worthwhile you to deliver benefit and mirror benefit jointly.
Even though the nonlinear coefficient of KTP crystal is massive, the laser hurt threshold is minimal, that will induce difficulties for instance refractive index adjust and transmission loss. BIBO crystal has better laser injury threshold and better second harmonic conversion performance. Whilst LBO and B-BBO are probably the most practical, They're small in dimension and possess certain hygroscopicity, even though BIBO crystals are non-soaked and can develop to massive dimensions. These positive aspects help BIBO crystals to get greatly used.
Crystals that are non-critically period-matched in a crystal oven may possibly show challenges once the crystal temperature is modified way too rapidly or also normally. Specifically, anti-reflection coatings may be ruined as a consequence of distinct thermal growth coefficients on the included products.
In many instances, a nonlinear crystal used for nonlinear frequency conversion has an extremely prolonged life time, which can be longer than that of The complete laser technique. The crystal material is basically not modified for the duration of Procedure. Nevertheless, a decreased crystal life span can arise below several situation:
芯飞睿所有的服务和支持都立足于使我们的客人工作的更加高效，更有价值。
The magnitude of the successful nonlinear coefficient depends upon the nonlinear tensor factors and within the used phase-matching configuration. A superior nonlinearity is significant especially Should the achievable optical intensities are lower.
Our crystals are Employed in a wide check here array of programs, including various styles of nonlinear frequency conversion and electro-optics, and also quantum know-how.
