The TSSG technique is a comparatively new procedure which has attained level of popularity for its ability to make superior-top quality crystals with lower defect density.
LBO has such excellent transmittance that it can even be accustomed to generate 266 nanometer light, although the absorption below 300nm is usually much too higher to the conversion being beneficial. In addition it shows Superb effectiveness for frequency conversion normally.
the chemical toughness; e.g., some crystal elements are hygroscopic, Other folks endure chemical variations when heated in the vacuum chamber for software of the dielectric coating
Last although not the very least, higher optical homogeneity ensures uniform gentle propagation with the crystal, leading to greater beam high quality and fewer distortions.
Many of the standard nonlinear crystals like BBO, LBO, BiBO or KTP for frequency doubling, tripling and quadrupling of the fundamental laser radiation can be obtained from inventory. Customer-certain Proportions and AR coatings also are provided at aggressive price ranges.
The selection of your most fitted crystal product for your supplied application is usually far from trivial; it need to include the thing to consider of numerous facets. For example, a large nonlinearity for frequency conversion of ultrashort pulses doesn't help If your conversation length is strongly limited by a large team velocity mismatch as well as the low hurt threshold boundaries the relevant optical intensities.
X-ray diffraction is a powerful method for figuring out the crystal structure and orientation of check here LBO nonlinear crystals.
These conditions, having said that, aren’t established in stone and mainly rely on the meant application on the crystal and also the intricacies of your laser method style and design. Frequently, with regard to temperature,
This carefully curated temperature profile makes sure that the mixture solidifies in a very uniform fashion, forming a single crystal structure. A important aspect of the Flux strategy may be the temperature gradient, which has a major effect on the size and high quality from the crystal. Ensuring a stable temperature gradient is vital for obtaining large, high-high-quality LBO Crystals.
Outside of substantial electric power lasers, this thermal security extends LBO Crystals�?applicability to a big range of environments with different temperature ailments.
Substantial intensity, quick pulse lasers with limited wavelengths have enabled quite a few producing procedures, or enhanced the results obtained from much more regular lasers. All those properties make possible a much more compact, even negligible HAZ (heat impacted zone) about the location of beam impingement.
Many different Homes of the nonlinear crystal might be essential for an application e.g. in nonlinear frequency conversion:
Sum-frequency technology (SFG) is a nonlinear method that entails the conversion of two enter photons into one output photon by using a frequency equal for the sum in the input frequencies. LBO nonlinear crystals have a significant nonlinear coefficient, that makes them ideal for effective SFG.
Crystals that are non-critically phase-matched in a very crystal oven may perhaps show challenges if the crystal temperature is modified also rapidly or much too generally. Specifically, anti-reflection coatings could be damaged resulting from diverse thermal expansion coefficients with the concerned materials.
