New middle infrared nonlinear optical crystals of BaGa2GeX6(X=S, Se) have been synthesized. The structures of the two BaGa2GeS6 and BaGa2GeSe6 were being identified to become isomorphous exhibiting a three-dimensional framework constructed with the parallel alignment of Ga or Ge tetrahedron groups alongside the c-aix. The ultraviolet transmittance spectrum suggests the brief-wavelength absorption edges of BaGa2GeS6 and BaGa2GeSe6 are 380 nm and 440 nm, respectively.
We crank out high-get harmonics from crystalline solids employing a tunable mid-IR OPA with 50 kHz repetition amount. Using nonlinear self-compression in YAG crystals, we produce sub a few-cycle pulses at 3.eight μm wavelength for top harmonic spectroscopy. Browse far more
New Center infrared nonlinear optical crystals of BaGa2GeX6(X=S, Se) are synthesized. The buildings of both of those BaGa2GeS6 and BaGa2GeSe6 had been uncovered for being isomorphous exhibiting a three-dimensional framework constructed because of the parallel alignment of Ga or Ge tetrahedron groups alongside the c-aix. The ultraviolet transmittance spectrum signifies the shorter-wavelength absorption edges of BaGa2GeS6 and BaGa2GeSe6 are 380 nm and 440 nm, respectively.
Which crystal form of ZrO//two is cryStallized from Zr(OH)//4 trusted the water vapor pressures during the crystallization phase. The contents of monoclinic crystals improved With all the water vapor pressures. Read much more
Intraband magnetotransmission and magnetophotoconductivity have been measured nearly 18 T employing CO2 laser strains. The cyclotron resonance and combined resonance harmonics are employed to determine the exchange interaction in an HgMnTe crystal. The experiment also evidences the freezing of electrons from the donor point out. Read much more

A high quality BGGSe single crystal with size of thirty mm×ninety mm was grown by Bridgman-stockbarger system, which is the main in China. The read more successful fabrication of BGGSe crystal units was also obtained just after orienting, reducing, and polishing processes, which laid a stable foundation with the more software exploration in the crystal.

$ rm BaGa _2 rm GeSe _6$ (BGGSe) is a newly developed nonlinear substance that is desirable for ultrabroad frequency mixing and ultrashort pulse era due to its comparably very low dispersion and substantial injury threshold. A numerical study shows the fabric’s capacity for octave-spanning mid-infrared pulse era up to 18 µm. In a primary experiment, we clearly show that a lengthy crystal duration of two.
It's proven that there are wavelength mixtures at which the effective nonlinearity coefficient may differ only a little bit in a broad frequency band.
BaGa2GeSe6 crystals are employed for nonlinear optical frequency conversion in their transparency range. The wavelengths at which optimum conversion efficiencies might be obtained and the tuning vary for difference-frequency era are identified.
