New middle infrared nonlinear optical crystals of BaGa2GeX6(X=S, Se) have been synthesized. The structures of the two BaGa2GeS6 and BaGa2GeSe6 had been located for being isomorphous exhibiting A 3-dimensional framework made by the parallel alignment of Ga or Ge tetrahedron teams together 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 crank out large-order harmonics from crystalline solids using a tunable mid-IR OPA with fifty kHz repetition fee. Applying nonlinear self-compression in YAG crystals, we crank out sub a few-cycle pulses at three.8 μm wavelength for top harmonic spectroscopy. Examine a lot more
New middle infrared nonlinear optical crystals of BaGa2GeX6(X=S, Se) are synthesized. The structures of each BaGa2GeS6 and BaGa2GeSe6 were being located to get isomorphous exhibiting a three-dimensional framework constructed because of the parallel alignment of Ga or Ge tetrahedron teams alongside the c-aix. The ultraviolet transmittance spectrum suggests the small-wavelength absorption edges of BaGa2GeS6 and BaGa2GeSe6 are 380 nm and 440 nm, respectively.
Take note: Author names might be searched within the key phrases subject, also, but which could discover papers where the person is outlined, instead of papers they authored.
The development of crystal expansion and laser output of BGSe and BGGSe are summarized, and the longer term progress is prospected.

Laser-induced damage threshold of the nonlinear crystals BaGa4Se7 and BaGa2GeSe6 at 2091 nm inside the nanosecond routine
24% that's comparable with one attained with significant repetition charge minimal-Strength laser techniques like in [nine]. Bearing in mind a possibility to extend pump pulse Electrical power of our setup as much as ~10 mJ, the DFG pulse Electricity may be enhanced around ~24 μJ at the same effectiveness, nonetheless, it essential a broad-aperture, ~fifteen mm in diameter BGGSe sample. Regular DFG pulse Power in AGS was not confidently measured with Ophir-3A electricity meter resulting from its reduced signal.
The habits of dislocations during the interfacial region in between the epitaxial layer developed through the liquid stage as well as the substrate of GaAs is investigated. Observations of dislocations lying along the 〈110�?Instructions click here ended up completed making use of an optical microscope following shallow etching having a new chemical etchant.
The highest frequency conversion performance of 10⁻⁴ was attained for a comparatively new PbIn6Te10 crystal, which can be an get of magnitude better than earlier benefits.
It can be revealed there are wavelength mixtures at which the successful nonlinearity coefficient differs only a little in a wide frequency band.
The nature of the instability and DFG Power decrease just isn't apparent for us. One among The explanations can be relevant which has a nonlinear absorption and plasma formation, respectively, that triggers reflection/scattering/absorption from the longwave mid-IR pulse. The dependence of BGGSe transmittance on pump pulse Electricity is presented in Fig.
