The data is saved using a YAML-based mostly structure, ensuring integrity, consistency, and relieve of obtain. Every history is accompanied by in depth metadata, facilitating a comprehensive comprehending and successful utilization of the information. During this descriptor, we outline the information curation protocols as well as the file format used for facts information, and briefly reveal how the information is often arranged inside a consumer-friendly fashion akin into the textbooks in a traditional library.
two–10.eight-µm wavelength location. A different critical limitation on the pump power connected having a thermal lensing impact in crystal was determined experimentally. A comparison was product of AgGaSe2 and ZnGeP2 crystals as resources suitable for the efficient generation of the second harmonic of cw CO2 laser radiation.

We crank out significant-order harmonics from crystalline solids using a tunable mid-IR OPA with fifty kHz repetition price. Utilizing nonlinear self-compression in YAG crystals, we deliver sub three-cycle pulses at three.8 μm wavelength for high harmonic spectroscopy. Examine extra
New Center infrared nonlinear optical crystals of BaGa2GeX6(X=S, Se) have been synthesized. The buildings of each BaGa2GeS6 and BaGa2GeSe6 were being identified for being isomorphous exhibiting A 3-dimensional framework constructed from the parallel alignment of Ga or Ge tetrahedron teams together the c-aix. The ultraviolet transmittance spectrum indicates the brief-wavelength absorption edges of BaGa2GeS6 and BaGa2GeSe6 are 380 nm and 440 nm, respectively.
Which crystal method of ZrO//2 is cryStallized from Zr(OH)//four depended on the h2o vapor pressures during the crystallization stage. The contents of monoclinic crystals greater Using the drinking water vapor pressures. Go through a lot more
The progress of crystal development and laser output of BGSe and BGGSe are summarized, and the future advancement is prospected.
77Growth of the new significant-effectiveness NLO crystal BaGa2GeSe6 by way of 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 is similar with one attained with substantial repetition charge small-Strength laser systems like in [9]. Taking into account a likelihood to enhance pump pulse Power of our setup as many as ~ten mJ, the DFG pulse Power might be greater nearly ~24 μJ at exactly the same effectiveness, even so, it expected a broad-aperture, ~15 mm in diameter BGGSe sample. Typical DFG pulse Power in AGS wasn't confidently calculated with Ophir-3A ability meter resulting from its reduced signal.
The behavior of dislocations from the interfacial location between the epitaxial layer grown in the liquid phase and also the substrate of GaAs is investigated. Observations of dislocations lying along the 〈a hundred and ten�?Instructions ended up completed making use of an optical microscope right after shallow etching having a new chemical etchant.
$ rm BaGa _2 rm GeSe _6$ (BGGSe) is often a freshly created nonlinear content that is certainly beautiful for ultrabroad frequency mixing and ultrashort pulse technology due to its comparably reduced dispersion and higher injury threshold. A numerical examine demonstrates the fabric’s capability for octave-spanning mid-infrared pulse era around 18 µm. In a primary experiment, we clearly show that a lengthy crystal size of 2.
Barium gallium germanium selenium (BaGa2GeSe6, BGGSe) crystal is often a novel infrared nonlinear optical material with fantastic general performance, which was learned by Chinese researchers. To this point, there isn't any report on massive dimension solitary crystal progress of this crystal in China. During this analyze, polycrystalline BGGSe was synthesized properly through the use get more info of a self-made two-zone furnace with the quantity of four hundred g in one operate.
