New middle infrared nonlinear optical crystals of BaGa2GeX6(X=S, Se) have already been synthesized. The constructions of both equally BaGa2GeS6 and BaGa2GeSe6 were being observed to get isomorphous exhibiting A 3-dimensional framework constructed from the parallel alignment of Ga or Ge tetrahedron groups alongside the c-aix. The ultraviolet transmittance spectrum indicates the shorter-wavelength absorption edges of BaGa2GeS6 and BaGa2GeSe6 are 380 nm and 440 nm, respectively.
We deliver high-buy harmonics from crystalline solids utilizing a tunable mid-IR OPA with 50 kHz repetition price. Employing nonlinear self-compression in YAG crystals, we produce sub a few-cycle pulses at three.eight μm wavelength for top harmonic spectroscopy. Browse a lot more

77Growth of the new superior-general performance NLO crystal BaGa2GeSe6 through the controlled vapor pressure approach
Laser-induced hurt threshold on the nonlinear crystals BaGa4Se7 and BaGa2GeSe6 at 2091 nm within the nanosecond routine
A top quality BGGSe solitary crystal with dimensions of 30 mm×ninety mm was developed by Bridgman-stockbarger strategy, which can be the primary in China. The effective fabrication of BGGSe crystal equipment here was also reached immediately after orienting, chopping, and polishing procedures, which laid a good Basis for the further more software study in the crystal.
The suitable Attributes and conventions utilized for the recently emerging acentric monoclinic crystals belonging towards the borate spouse and children are summarized and tabulated. The derivations are anticipated that can help establish adherence to uniform nomenclature and conventions for these novel inorganic nonlinear crystals, also to get rid of ambiguity and raising confusion during the literature and in the industrial requirements. The final expressions to the successful nonlinearity are minimized for triclinic crystals of issue team 1 to simplified sorts while in the principal planes.
$ rm BaGa _2 rm GeSe _6$ (BGGSe) is usually a recently created nonlinear product that's eye-catching for ultrabroad frequency mixing and ultrashort pulse technology resulting from its comparably reduced dispersion and superior harm threshold. A numerical research demonstrates the fabric’s capacity for octave-spanning mid-infrared pulse technology up to 18 µm. In a primary experiment, we demonstrate that a long crystal duration of two.

The nature of the instability and DFG Electricity lower just isn't obvious for us. Considered one of The explanations may be similar with a nonlinear absorption and plasma formation, respectively, that causes reflection/scattering/absorption of your longwave mid-IR pulse. The dependence of BGGSe transmittance on pump pulse energy is offered in Fig.
