The data is saved using a YAML-dependent format, making sure integrity, consistency, and relieve of obtain. Each and every history is accompanied by detailed metadata, facilitating a comprehensive comprehension and economical utilization of the data. With this descriptor, we define the data curation protocols along with the file structure used for data data, and briefly reveal how the information is usually arranged in the person-helpful vogue akin into the textbooks in a traditional library.
2–ten.eight-µm wavelength area. Yet another significant limitation with the pump power related using a thermal lensing result in crystal was determined experimentally. A comparison was fabricated from AgGaSe2 and ZnGeP2 crystals as elements ideal for the efficient generation of the 2nd harmonic of cw CO2 laser radiation.

Numerous courses of IR NLO components with fantastic In general overall performance have already been located, which include BaGa4Se7 and BaGa2GeSe6. Also, the analysis on these supplies has long gone further than crystal composition and preliminary characterization. Fantastic endeavours are already carried out in the majority crystal advancement, while in the thorough measurement in their Bodily Qualities working with bulk crystals, from the evaluation in their IR laser output efficiency, and inevitably inside the fabrication of laser system. Inside the frequency down-conversion OPOs pumped by the standard 1 µm laser, BaGa4Se7 has recognized the stable output of mid-significantly IR laser output with the highest energy and widest wavelength array to date. On this evaluate, rather than masking all compounds with IR NLO Homes, our discussion will only deal with All those exhibiting excellent In general IR NLO functionality and application prospect, especially on Those people of which substantial measurement one crystals happen to be already received. This evaluation then concludes by having an outlook on what efforts may very well be built Sooner or later.
The pc you're using just isn't registered by an institution having a membership to this information. You should choose one of the choices below.
New Center infrared nonlinear optical crystals of BaGa2GeX6(X=S, Se) are synthesized. The buildings of the two BaGa2GeS6 and BaGa2GeSe6 ended up uncovered for being isomorphous exhibiting A 3-dimensional framework built via the parallel alignment of Ga or Ge tetrahedron groups along the c-aix. The ultraviolet transmittance spectrum indicates the brief-wavelength absorption edges of BaGa2GeS6 and BaGa2GeSe6 are 380 nm and 440 nm, respectively.
A thermo-optic dispersion system for BaGa2GeSe6 rm BaGa _2 rm GeSe _6 B a G a 2 G e S e six nonlinear crystal is described. The experimentally established temperature-dependent period-matching problems for second-harmonic and sum-frequency generation of Nd:YAG laser-pumped KTiOPO4 rm KTiOPO _4 K T i O P O 4 (KTP) and RbTiOAsO4 rm RbTiOAsO _4 R b T i O A s O 4 (RTA) optical parametric oscillators as well as a CO2 rm CO _2 C O two laser and its harmonics in the 0.
Intraband magnetotransmission and magnetophotoconductivity have been measured approximately eighteen T working with CO2 laser lines. The cyclotron resonance and combined resonance harmonics are utilized to determine the Trade conversation within an HgMnTe crystal. The experiment also evidences the freezing of electrons inside the donor condition. Read much more

24% which happens to be comparable with one acquired with superior repetition charge small-Strength laser devices like in [9]. Taking into consideration a possibility to enhance pump pulse energy of our set up as much as ~10 mJ, the DFG pulse Power is usually elevated up to ~24 μJ at the exact same performance, even so, it needed a large-aperture, ~fifteen mm in diameter BGGSe sample. Common DFG pulse Vitality in AGS wasn't confidently measured with Ophir-3A power meter due to its low signal.
It has been identified which the optical nonlinear coefficients d31 and d22 in LiNbO3 are of reverse sign, in disagreement with the earlier report by Other folks. This is a vital thing to consider for optimizing nonlinear optical interactions in LiNbO3.
$ rm BaGa _2 rm GeSe _6$ (BGGSe) is a newly formulated nonlinear content which is appealing for ultrabroad frequency mixing and ultrashort pulse era on account of its comparably low dispersion and significant damage threshold. A numerical analyze demonstrates the material’s potential for octave-spanning mid-infrared pulse generation as many as eighteen µm. In a first experiment, we exhibit that a long crystal length of 2.
Barium gallium germanium selenium (BaGa2GeSe6, BGGSe) crystal is actually a novel infrared nonlinear optical material with fantastic effectiveness, which was uncovered by Chinese researchers. To date, there is no report on substantial dimension solitary crystal growth of this crystal in China. In this examine, polycrystalline BGGSe was synthesized correctly by using a self-designed two-zone furnace with the level of 400 g in a single operate.
BaGa2GeSe6 crystals are employed for nonlinear optical frequency conversion inside their transparency array. The wavelengths at which most conversion efficiencies click here is usually attained and also the tuning range for distinction-frequency generation are discovered.
