If you don't find the appropriate merchandise earlier mentioned, you could possibly let's know your necessities or apps in the form underneath. Our sales or complex team can get again for you at the earliest opportunity.
If the crystal surfaces remain “soiled�?immediately after the above cleansing procedures, the surfaces might have been broken. Make sure you Make contact with us for rework in the crystals.

The level of the solvent could be adjusted for several crystal measurement so the lens tissue is retained damp for the whole drag but there is not any visible trace of solvent about the crystal surface area once the drag is finished. Inspect the floor and repeat if essential, but only use Each individual sheet of lens tissue when.
Also, it could be remarkably appealing to make use of a crystal product which may be critically phase-matched at place temperature due to the fact noncritical phase matching frequently entails the Procedure in the crystal in the temperature-stabilized crystal oven. Even so, the feasibility of critical stage matching may very well be provided just for adequately higher peak powers.
Dust and stains on crystal surfaces can result in scattering/loss of sunshine and can even respond with mild to wreck optical surfaces at a higher incident laser energy.
At present, as a kind of fantastic nonlinear next harmonic crystal, it may be used to make substantial effectiveness crystal of inexperienced or blue laser.
Bismuth Triborate (BiB3O6 or BIBO) is often a freshly formulated nonlinear optical crystal. It possesses massive efficient nonlinear coefficient, superior hurt threshold and inertness with respect to moisture.
Although the nonlinear coefficient of KTP crystal is massive, the laser damage threshold is lower, that will lead to problems for instance refractive index adjust and transmission decline. BIBO crystal has larger laser problems threshold and better next harmonic conversion efficiency. Though LBO and B-BBO are the most sensible, They can be smaller in sizing and have sure hygroscopicity, while BIBO crystals are non-wet and can grow to huge dimensions. These advantages enable BIBO crystals to be greatly made use of.
Borates for instance LBO and BBO also do the job effectively in broadly tunable optical parametric oscillators and optical parametric chirped-pulse amplification.
Non-linear Optical (NLO) crystals offer an enormously versatile Option for generating new wavelengths from existing, off-the-shelf laser sources. The optical wavelength spectrum is utilized by a big and constantly increasing range of apps, from production of clinical lasers, quantum networking & computing via to environmental sensing in addition to several Other individuals.
GWU-Lasertechnik gives all normal nonlinear crystals like LBO, BBO and KTP having a broad range of specifications. Beside the perfectly-proven elements, innovative crystals like CLBO or BiBO with exceptional Houses for e. g. deep-UV technology or high-ability ultrashort pulse lasers are available. No matter if unique pieces for R & D reasons are necessary or Price-efficient more info quantities in modest, medium or large batches with in-time supply for your manufacturing line are needed: GWU’s committed support helps to locate the greatest Main elements to your software.
linear absorption, which can result in heating at superior optical energy stages, so which the section matching is disturbed, and thermal lensing may take place
Superior Destruction Threshold: BIBO crystal contains a superior problems threshold, letting it to resist large laser energy without the need of struggling damage. This attribute can make BIBO ideal for use in high-electric power laser techniques.
