The TSSG system is a comparatively new approach which includes obtained popularity for its power to deliver substantial-good quality crystals with lower defect density.
Lithium niobate (LiNbO3) and lithium tantalate (LiTaO3) are supplies with a comparatively powerful nonlinearity. They in many cases are utilized for nonlinear frequency conversion in addition to for electro-optic modulators. The two resources are available in congruent and in stoichiometric form, with crucial discrepancies regarding periodic poling and photorefractive effects (see beneath). Lithium niobate and tantalate will be the most often employed supplies inside the context of periodic poling; the resulting supplies are identified as PPLN (periodically poled lithium niobate) and PPLT, respectively, or PPSLN and PPSLT for that stoichiometric variations.
These features decrease the alignment sensitivity of the optical program and make certain greater beam propagation. The fewer stringent alignment prerequisites and improved beam high-quality conferred by these characteristics usually tip the size in favor of LBO Crystals above other nonlinear optical crystals.
Observe that regardless of whether the nominal depth is beneath the nominal problems threshold, there might be troubles because of fluctuations in the beam electric power or nearby intensity (e.g., if a beam profile has “very hot places�?, or resulting from isolated defects in a crystal, which happen to be more sensitive than the standard crystal product.
It really is worthy of noting that the characterization solutions mentioned During this chapter are not restricted to LBO nonlinear crystals and might be applied to other nonlinear crystals at the same time.
Total, The mixing of LBO Crystals into laser technological innovation has pushed the boundaries of what we can obtain with light-weight, lights The trail toward a brighter, extra illuminated upcoming.
Optical microscopy can be employed to recognize surface area defects, for example scratches, cracks, and more info pits, that could have an impact on the general performance from the crystal in many programs. Optical microscopy will also be utilized to determine the crystal thickness and uniformity.
GWU-Lasertechnik provides all regular nonlinear crystals like LBO, BBO and KTP using a wide range of specifications. Beside the very well-proven supplies, progressive crystals like CLBO or BiBO with outstanding properties for e. g. deep-UV generation or high-electric power ultrashort pulse lasers are offered. It does not matter if person items for R & D needs are expected or Price tag-efficient numbers in compact, medium or big batches with in-time shipping to the creation line are required: GWU’s dedicated assistance helps to discover the very best Main parts for your application.
Optical microscopy is really a generally employed strategy for characterizing the floor morphology and defects in LBO nonlinear crystals. Optical microscopy includes illuminating the crystal having a beam of sunshine and observing the reflected or transmitted mild through a microscope. By examining the area morphology and defects, the crystal good quality can be identified.
Over and above large electric power lasers, this thermal steadiness extends LBO Crystals�?applicability to your wide array of environments with various temperature problems.
Significant intensity, brief pulse lasers with short wavelengths have enabled many manufacturing procedures, or improved the outcome attained from extra common lasers. Those people properties make doable a Significantly smaller sized, even negligible HAZ (warmth impacted zone) all around the location of beam impingement.
Just about the most common programs is frequency doubling, the place LBO Crystals competently convert the frequency of the significant electrical power laser, effectively halving the wavelength and opening up a spectrum of alternatives for laser programs.
For client advantage and defense of crystals, common 1" anodized aluminum (Al) mounts is usually made available upon request. The mounted crystals is often even more mounted in a standard 1" mirror mount to generally be angle tuned for stage matching (
The idea of these procedures is very important for the look and optimization of crystal development processes as well as creation of substantial-good quality LBO nonlinear crystals for different purposes in optics and photonics.
