The susceptibility to humidity of BiBO is very reduced. Even so, people are suggested to offer dry situations for both of those use and storage of BiBO to lengthen the life span. H2o condensation on crystal surfaces really should be absolutely averted at any time.
In addition, it has a crucial software in successful generation of ultrabright entangled photons by means of blue pumped spontaneous parametric down conversions (SPDC).

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

Take note that regardless of whether the nominal depth is beneath the nominal hurt threshold, there might be problems because of fluctuations inside the beam energy or area depth (e.g., if a beam profile has “scorching places�?, or resulting from isolated defects in a crystal, which happen to be a lot more delicate compared to regular crystal material.
Crylink can be an open up System, just as our mission is to attach benefit, Crylink thinks that every more info human being and every enterprise has special worth, and we hope to connect with useful you to provide price and reflect price jointly.
Although the nonlinear coefficient of KTP crystal is significant, the laser problems threshold is lower, that may trigger complications including refractive index alter and transmission decline. BIBO crystal has larger laser damage threshold and better next harmonic conversion efficiency. Although LBO and B-BBO are quite possibly the most functional, They're small in dimensions and also have specific hygroscopicity, although BIBO crystals are non-soaked and might increase to significant dimension. These benefits allow BIBO crystals to get widely used.
Numerous properties of the nonlinear crystal could be crucial for an software e.g. in nonlinear frequency conversion:
In several scenarios, a nonlinear crystal useful for nonlinear frequency conversion has an exceptionally lengthy life span, that is more time than that of the whole laser process. The crystal product is essentially not modified during Procedure. However, a minimized crystal life time can come about under a variety of situations:
GWU-Lasertechnik presents all standard nonlinear crystals like LBO, BBO and KTP which has a wide number of requirements. Beside the properly-set up supplies, impressive crystals like CLBO or BiBO with exceptional Attributes for e. g. deep-UV technology or large-power ultrashort pulse lasers are available. Irrespective of if unique pieces for R & D purposes are required or Expense-successful numbers in compact, medium or massive batches with in-time delivery for your manufacturing line are essential: GWU’s dedicated company helps to discover the finest core components for the software.
Optical crystals can exhibit various kinds of optical nonlinearities, which may be utilized in several techniques:
flux-developed KTP and RTP with its substantial nonlinearity, also in variants with higher grey monitoring resistance
