The susceptibility to dampness of BiBO is rather lower. On the other hand, consumers are recommended to supply dry situations for both use and storage of BiBO to extend the life time. Drinking water condensation on crystal surfaces ought to be absolutely avoided Anytime.
If the crystal surfaces remain “filthy�?after the above cleaning treatments, the surfaces might have been harmed. Be sure to Speak to us for rework on the crystals.
A lot of the common nonlinear crystals like BBO, LBO, BiBO or KTP for frequency doubling, tripling and quadrupling of the basic laser radiation are available from stock. Shopper-certain Proportions and AR coatings can also be available at competitive selling prices.
Crystal life time can also be strongly dependent on the material good quality, Whilst selected degradation phenomena appear to be intrinsic limitations of the material.
Also, it may be hugely appealing to utilize a crystal product which can be critically section-matched at area temperature for the reason that noncritical section matching normally will involve the Procedure with the crystal in a temperature-stabilized crystal oven. Nevertheless, the feasibility of critical section matching may very well be presented only for adequately higher peak powers.

At the moment, as A sort of wonderful nonlinear second harmonic crystal, it can be used to produce large efficiency crystal of inexperienced or blue laser.
Operation of nonlinear crystals at temperatures below home temperature (to realize stage matching) is usually problematic, as it could bring on condensation of drinking water around the crystal surfaces if the bordering air isn't quite dry.
In the situation of ultrashort pulses the superior team velocity mismatch enforces using a shorter crystal, which needs significant optical intensities for the presented conversion effectiveness.
Excessive optical intensities all through operation may perhaps promptly hurt a crystal. Sad to say, nonlinear crystals typically should be operated not far from their optical harm threshold to attain a adequately superior conversion performance. This means a trade-off in between conversion performance and crystal life time.
In several instances, a nonlinear crystal utilized for nonlinear frequency conversion has an exceptionally long lifetime, that's for a longer time than that of The full laser system. The crystal materials is actually not modified all through operation. Having said that, a decreased crystal life time can take place below different conditions:
GWU-Lasertechnik delivers all standard nonlinear crystals like LBO, BBO and KTP having a broad assortment of specifications. Beside the nicely-established resources, modern crystals like CLBO or BiBO with click here exceptional Houses for e. g. deep-UV technology or large-energy ultrashort pulse lasers can be obtained. It doesn't matter if person parts for R & D uses are essential or Charge-productive quantities in smaller, medium or huge batches with in-time supply for the output line are wanted: GWU’s committed support helps to discover the best Main factors for your application.
linear absorption, that may bring about heating at higher optical electricity concentrations, so the phase matching is disturbed, and thermal lensing might happen
flux-grown KTP and RTP with its significant nonlinearity, also in variants with high grey monitoring resistance
