The info is saved utilizing a YAML-based structure, making sure integrity, consistency, and relieve of accessibility. Every single record is accompanied by in-depth metadata, facilitating an extensive knowing and economical utilization of the information. During this descriptor, we define the data curation protocols and the file structure used for data data, and briefly reveal how the data may be arranged in a very consumer-pleasant manner akin on the publications in a conventional library.
two–10.eight-µm wavelength region. An additional critical limitation on the pump electric power connected which has a thermal lensing influence in crystal was determined experimentally. A comparison was crafted from AgGaSe2 and ZnGeP2 crystals as materials ideal for the efficient era of the 2nd harmonic of cw CO2 laser radiation.

New Center infrared nonlinear optical crystals of BaGa2GeX6(X=S, Se) happen to be synthesized. The structures of the two BaGa2GeS6 and BaGa2GeSe6 had been observed to be isomorphous exhibiting a three-dimensional framework constructed by the parallel alignment of Ga or Ge tetrahedron groups together the c-aix. The ultraviolet transmittance spectrum suggests the shorter-wavelength absorption edges of BaGa2GeS6 and BaGa2GeSe6 are 380 nm and 440 nm, respectively.

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 documented. The experimentally identified temperature-dependent phase-matching situations for 2nd-harmonic and sum-frequency era 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 2 laser and its harmonics within the 0.
Intraband magnetotransmission and magnetophotoconductivity have been measured up to 18 T using CO2 laser traces. The cyclotron resonance and mixed resonance harmonics are utilised to determine the exchange interaction in an HgMnTe crystal. The experiment also evidences the freezing of electrons within the donor point out. Examine extra
During the final many years, mid-infrared (3–twelve μm) laser sources making use of crystals with nonlinear optical properties have attracted a selected notice due to their likely purposes in numerous fields for example optical counter-steps and distant chemical sensing. As transparency of widespread oxide crystals is limited to about 4 μm, quite a few researches are already centered on chalcopyrite compounds as a result of their huge transparency inside the mid-IR array as well as their robust nonlinear optical coefficients. You will find a require of these kinds of crystals website equipped to transform effectively the around infrared wavelengths from commercially available lasers into wavelengths bigger than five μm through Optical Parametric Oscillators (OPO) devices.

A high quality BGGSe single crystal with measurement of thirty mm×ninety mm was grown by Bridgman-stockbarger system, which happens to be the primary in China. The productive fabrication of BGGSe crystal gadgets was also accomplished just after orienting, slicing, and sprucing procedures, which laid a stable Basis for your even further application study of the crystal.
The actions of dislocations during the interfacial area in between the epitaxial layer developed through the liquid stage as well as substrate of GaAs is investigated. Observations of dislocations lying together the 〈one hundred ten�?directions had been performed working with an optical microscope following shallow etching that has a new chemical etchant.
46 m duration stuffed by CO2 at 3 atm fuel tension in which the laser pulse was broadened due to self-stage modulation underneath filamentation. Then, the pump and sign pulses ended up combined with each other. Some time correlation with the pump and signal pulses was managed by the pump pulse arm size with the adjustment of mirror M3 placement.
It truly is revealed there are wavelength mixtures at which the successful nonlinearity coefficient differs only slightly in a wide frequency band.
The character of the instability and DFG Vitality reduce just isn't obvious for us. Considered one of the reasons may be relevant by using a nonlinear absorption and plasma formation, respectively, that triggers reflection/scattering/absorption on the longwave mid-IR pulse. The dependence of BGGSe transmittance on pump pulse Electricity is introduced in Fig.
