New Center infrared nonlinear optical crystals of BaGa2GeX6(X=S, Se) happen to be synthesized. The buildings of the two BaGa2GeS6 and BaGa2GeSe6 were being located to be isomorphous exhibiting a three-dimensional framework constructed with the parallel alignment of Ga or Ge tetrahedron teams together the c-aix. The ultraviolet transmittance spectrum indicates the limited-wavelength absorption edges of BaGa2GeS6 and BaGa2GeSe6 are 380 nm and 440 nm, respectively.
We produce substantial-get harmonics from crystalline solids employing a tunable mid-IR OPA with 50 kHz repetition charge. Working with nonlinear self-compression in YAG crystals, we generate sub three-cycle pulses at 3.eight μm wavelength for prime harmonic spectroscopy. Study far more

Laser-induced damage threshold in the nonlinear crystals BaGa4Se7 and BaGa2GeSe6 at 2091 nm while in the nanosecond routine
The uniaxial nonlinear crystals BaGa2GeS6 and BaGa2GeSe6 are characterized concerning thermal diffusivity and particular heat about a temperature range of -90 to 250 °C for heat propagation alongside and perpendicular to your c -axis.
It's been located the optical nonlinear coefficients d31 and d22 in LiNbO3 are of opposite indication, in disagreement having an previously report by Other folks. This is an important consideration for optimizing nonlinear optical interactions in LiNbO3.
$ rm BaGa _2 rm GeSe _6$ (BGGSe) is actually a recently produced nonlinear content that is more info certainly beautiful for ultrabroad frequency mixing and ultrashort pulse era as a consequence of its comparably lower dispersion and large injury threshold. A numerical examine exhibits the material’s potential for octave-spanning mid-infrared pulse technology approximately 18 µm. In a first experiment, we show that a protracted crystal duration of two.
