XRD entails shining a beam of X-rays on to the crystal and measuring the depth and path with the scattered X-rays. By analyzing the scattered X-rays, the crystal composition and orientation can be established.
LBO has these terrific transmittance that it may even be utilized to crank out 266 nanometer gentle, although the absorption down below 300nm is usually much too high for your conversion being handy. It also displays very good efficiency for frequency conversion normally.
Even very well under the threshold for instant problems, some crystal components exhibit a steady degradation in the utilized volume, e.
Notice that even if the nominal intensity is under the nominal damage threshold, there might be issues as a consequence of fluctuations while in the beam energy or neighborhood intensity (e.g., if a beam profile has “warm places�?, or as a consequence of isolated defects in a crystal, that are far more delicate in comparison to the normal crystal materials.
linear absorption, which may induce heating at high optical electric power ranges, so that the period matching is disturbed, and thermal lensing may possibly occur
A typical approach for getting ultrathin crystals is usually to to start with optically Call a thicker nonlinear crystal with a few substrate (e.g. of fused silica) and afterwards to shine the crystal down to the necessary thickness of e.
SHG and THG for middle and large energy Nd: lasers at 1064 nm for healthcare, industrial and armed service purposes
GWU-Lasertechnik gives all normal nonlinear crystals like LBO, BBO and KTP having a broad variety of requirements. Beside the well-set up materials, impressive crystals like CLBO or BiBO with outstanding Homes for e. g. deep-UV generation or substantial-electric power ultrashort pulse lasers can be obtained. It doesn't matter if particular person pieces for R & D uses are necessary or Price tag-economical numbers in modest, medium or significant batches with in-time shipping to the production line are desired: GWU’s focused provider really helps to locate the best core factors to your application.
In the situation of ultrashort pulses the significant team velocity mismatch enforces the usage of a shorter crystal, which calls for significant optical intensities to get a specified conversion efficiency.
Overall, the characterization procedures talked about Within this chapter provide precious insights in to the solutions used for the characterization of LBO nonlinear crystals.
Inspect the crystal surface area for dust and stains by holding it close to a vibrant visible-gentle source. Viewing at various angles may also help see scattering from dust and stains. The crystal surface must be cleaned as explained below if dust and stains are discovered.
The magnitude on the efficient nonlinear coefficient depends upon read more the nonlinear tensor parts and around the used phase-matching configuration. A substantial nonlinearity is important significantly In the event the achievable optical intensities are very low.
The most common process for accomplishing period-matching in LBO nonlinear crystals is angle tuning, in which the crystal is rotated to locate the optimal angle that satisfies the section-matching affliction.
They can endure significant warmth with none major efficiency reduction, guaranteeing that your optical technique continues to be reliable and productive even in demanding situations.
