The data is stored utilizing a YAML-based mostly format, guaranteeing integrity, regularity, and simplicity of accessibility. Each document is accompanied by in depth metadata, facilitating a comprehensive understanding and productive utilization of the info. With this descriptor, we outline the data curation protocols plus the file structure useful for knowledge documents, and briefly show how the information is often organized within a person-helpful style akin for the publications in a traditional library.
To get use of this information, you should comprehensive the advice Form and we will comply with up together with your librarian or Institution on your own behalf.
We existing new experimental results for your stage-matching Homes of your just lately discovered BaGa2GeSe6
New middle infrared nonlinear optical crystals of BaGa2GeX6(X=S, Se) are actually synthesized. The structures of both of those BaGa2GeS6 and BaGa2GeSe6 were uncovered to get isomorphous exhibiting A 3-dimensional framework created with the parallel alignment of Ga or Ge tetrahedron groups along the c-aix. The ultraviolet transmittance spectrum indicates the quick-wavelength absorption edges of BaGa2GeS6 and BaGa2GeSe6 are 380 nm and 440 nm, respectively.
We generate substantial-buy harmonics from crystalline solids using a tunable mid-IR OPA with fifty kHz repetition amount. Employing nonlinear self-compression in YAG crystals, we deliver sub three-cycle pulses at 3.eight μm wavelength for high harmonic spectroscopy. Examine additional
The dislocations are traced because of the repetition of etching from epitaxial layer to the interface. The outcome demonstrate that dislocations within the substrates are expected to bend together the route ordinary to the epitaxial advancement course in the interface.
A thermo-optic dispersion system for BaGa2GeSe6 rm BaGa _2 rm GeSe _6 B a G a two G e S e 6 nonlinear crystal is documented. The experimentally established temperature-dependent stage-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 four (RTA) optical parametric oscillators as well as a CO2 rm CO _2 C O 2 laser and its harmonics while in the 0.
The development of crystal expansion and laser output of BGSe and BGGSe are summarized, and the future progress is prospected.

Laser-induced destruction threshold from the nonlinear crystals BaGa4Se7 and BaGa2GeSe6 at 2091 nm inside the nanosecond BaGa2GeSe6 Crystal regime
A high quality BGGSe one crystal with measurement of thirty mm×90 mm was grown by Bridgman-stockbarger system, and that is the main in China. The profitable fabrication of BGGSe crystal devices was also accomplished after orienting, cutting, and polishing processes, which laid a stable Basis with the additional software research of your crystal.
A thermo-optic dispersion formula for BaGa2GeSe6 rm BaGa _2 rm GeSe _6 B a G a two G e S e 6 nonlinear crystal is described. The experimentally decided temperature-dependent stage-matching problems for next-harmonic and sum-frequency era of Nd:YAG laser-pumped KTiOPO4 rm KTiOPO _4 K T i O P O four (KTP) and RbTiOAsO4 rm RbTiOAsO _4 R b T i O A s O four (RTA) optical parametric oscillators as well as a CO2 rm CO _2 C O 2 laser and its harmonics from the 0.
46 m length crammed by CO2 at 3 atm gasoline strain in which the laser pulse was broadened because of self-stage modulation less than filamentation. Then, the pump and sign pulses were blended with each other. Enough time correlation with the pump and signal pulses was controlled with the pump pulse arm size from the adjustment of mirror M3 position.
Barium gallium germanium selenium (BaGa2GeSe6, BGGSe) crystal can be a novel infrared nonlinear optical materials with great efficiency, which was found by Chinese scientists. To date, there isn't a report on huge sizing single crystal growth of the crystal in China. On this review, polycrystalline BGGSe was synthesized successfully by utilizing a self-manufactured two-zone furnace with the level of 400 g in a single run.
BaGa2GeSe6 crystals are utilized for nonlinear optical frequency conversion within their transparency assortment. The wavelengths at which highest conversion efficiencies could be received as well as tuning range for difference-frequency era are found.
