The data is saved utilizing a YAML-based structure, guaranteeing integrity, consistency, and ease of entry. Each history is accompanied by comprehensive metadata, facilitating a comprehensive being familiar with and successful utilization of the info. In this particular descriptor, we outline the info curation protocols as well as file format useful for knowledge records, and briefly show how the information might be arranged inside a consumer-helpful manner akin into the books in a conventional library.
We derive explicit expressions in the frame of the optical indicatrix for the next-purchase efficient nonlinearity in biaxial crystals with place teams 2, m, and one, governing the conversion efficiency in 3-wave nonlinear optical interactions. The tabulated expressions to the monoclinic symmetry classes two and m are legitimate for all attainable orientations of the optical indicatrix relative into the crystallographic body and for propagation along an arbitrary course outside the principal planes. They may be used for immediate estimation of the productive nonlinearity in precisely the same body the place the section-matching loci are calculated.
spectral range. In addition, we present new Sellmeier equations that provide a good replica on the

We generate large-buy harmonics from crystalline solids utilizing a tunable mid-IR OPA with fifty kHz repetition charge. Utilizing nonlinear self-compression in YAG crystals, we create sub 3-cycle pulses at 3.eight μm wavelength for top harmonic spectroscopy. Browse more
The dislocations are traced by the repetition of etching from epitaxial layer into the interface. The final results present that dislocations in the substrates are predicted to bend together the way ordinary to the epitaxial advancement route within the interface.
0 Abstract Abstract: BaGa4Se7 (BGSe) and BaGa2GeSe6 (BGGSe) crystals are novel infrared nonlinear optical resources independently made by Chinese experts. Because of the great comprehensive overall performance as well as the crucial application worth in laser sector, they have got attracted Significantly consideration at your house and abroad.
When utilizing an institutional account for this Web page we don’t keep track of any private, general performance, functional or 1st or third get together linked information.
77Growth of The brand new significant-effectiveness NLO crystal BaGa2GeSe6 through the managed vapor stress process
Laser-induced damage threshold of your nonlinear crystals BaGa4Se7 and BaGa2GeSe6 at 2091 nm from the nanosecond regime
24% which can be comparable with just one received with large repetition charge small-Strength laser devices like in [nine]. Bearing in mind a possibility to raise pump pulse Power of our set up around ~10 mJ, the DFG pulse Electrical power could be increased around ~24 μJ at the exact same effectiveness, even so, it needed a wide-aperture, ~15 mm in diameter BGGSe sample. Normal DFG pulse energy in AGS wasn't confidently calculated with Ophir-3A electricity meter resulting from its small sign.
The relevant Homes and conventions employed for the recently emerging acentric monoclinic crystals belonging into the borate household are summarized and tabulated. The derivations are expected to aid set up adherence to uniform nomenclature and conventions for these novel inorganic nonlinear crystals, and to eliminate ambiguity and raising confusion from the literature As well as in the commercial technical specs. The overall expressions for the powerful nonlinearity are decreased for triclinic crystals of position group 1 to simplified sorts inside the principal planes.
$ rm BaGa _2 rm GeSe _6$ (BGGSe) is often a newly made nonlinear content that's eye-catching for ultrabroad frequency mixing and ultrashort pulse generation on account of its comparably low dispersion and superior damage threshold. A get more info numerical examine displays the material’s capability for octave-spanning mid-infrared pulse generation as many as 18 µm. In a primary experiment, we display that a lengthy crystal length of 2.
Barium gallium germanium selenium (BaGa2GeSe6, BGGSe) crystal is really a novel infrared nonlinear optical content with excellent performance, which was discovered by Chinese researchers. To date, there is absolutely no report on large dimensions solitary crystal progress of the crystal in China. With this analyze, polycrystalline BGGSe was synthesized productively through the use of a self-made two-zone furnace with the amount of 400 g in one run.
The nature of this instability and DFG Power reduce just isn't clear for us. One among the reasons may be associated which has a nonlinear absorption and plasma formation, respectively, that triggers reflection/scattering/absorption from the longwave mid-IR pulse. The dependence of BGGSe transmittance on pump pulse Power is offered in Fig.
