Hygroscopic crystal elements deteriorate when they are not always saved in sufficiently dry air (or a dry purge gasoline). This applies e.g. to KDP and BBO, As well as in a lesser extent to LBO. It may be practical to help keep this kind of crystal at a to some degree elevated temperature, which makes it much easier to continue to keep it dry.
Kingwin Optics offers large-excellent BIBO crystal with Sophisticated coatings and mounting possibilities, rendering it an excellent choice for researchers, engineers, and makers trying to get economical and responsible nonlinear optical factors.

Also, it can be really desirable to work with a crystal content that may be critically stage-matched at space temperature mainly because noncritical period matching typically will involve the operation on the crystal within a temperature-stabilized crystal oven. On the other hand, the feasibility of crucial phase matching could be given only for adequately high peak powers.
GWU-Lasertechnik has much more than 30 many years of expertise in distributing laser crystals. Pick GWU to get pleasure from our vast awareness and in-subject working experience!
Observe that although the nominal depth is underneath the nominal problems threshold, there might be difficulties on account of fluctuations inside the beam electrical power or neighborhood intensity (e.g., if a beam profile has “warm places�?, or on account of isolated defects within a crystal, that are more delicate compared to typical crystal material.
Procedure of nonlinear crystals at temperatures under area temperature (to realize section matching) is usually problematic, as it may well lead to condensation of drinking water around the crystal surfaces When the bordering air will not be extremely dry.
Even though the nonlinear coefficient of KTP crystal is big, the laser damage threshold is lower, that may result in problems like refractive index adjust and transmission reduction. BIBO crystal has higher laser hurt threshold and better 2nd harmonic conversion performance. Even though LBO and B-BBO are one of the most simple, They can be tiny in dimension and have selected hygroscopicity, whilst BIBO crystals are non-wet and may increase to huge sizing. These pros enable BIBO crystals to get extensively applied.
Crystals which are non-critically period-matched inside a crystal oven might show troubles if the crystal temperature is altered much too swiftly or much too typically. Especially, anti-reflection coatings could be weakened read more on account of distinctive thermal expansion coefficients with the involved resources.
Bismuth Triborate (BiB3O6 or BIBO) is usually a newly produced nonlinear optical crystal. It possesses massive helpful nonlinear coefficient, higher hurt threshold and inertness with regard to humidity.
This combination makes BIBO crystal extremely suited for harnessing the phenomenon of second harmonic technology (SHG) within just reliable-state lasers and laser diodes.
Optical crystals can exhibit unique forms of optical nonlinearities, that may be used in a variety of techniques:
flux-developed KTP and RTP with its significant nonlinearity, also in variants with significant gray tracking resistance
