The Ultimate Guide To BaGa2GeSe6 Crystal
Blog Article
BaGa4Se7 (BGSe) and BaGa2GeSe(BGGSe) crystals are novel infrared nonlinear optical products independently created by Chinese researchers. As a result of great comprehensive functionality plus the critical application benefit in laser field, they may have captivated Substantially attention at your home and overseas.
We derive express expressions while in the body on the optical indicatrix for the 2nd-order powerful nonlinearity in biaxial crystals with point groups 2, m, and 1, governing the conversion effectiveness in a few-wave nonlinear optical interactions. The tabulated expressions for your monoclinic symmetry lessons two and m are valid for all possible orientations in the optical indicatrix relative for the crystallographic frame and for propagation together an arbitrary route exterior the principal planes. They can be useful for direct estimation of your productive nonlinearity in the same frame where by the phase-matching loci are calculated.

New middle infrared nonlinear optical crystals of BaGa2GeX6(X=S, Se) are already synthesized. The structures of equally BaGa2GeS6 and BaGa2GeSe6 ended up uncovered to be isomorphous exhibiting a three-dimensional framework made through the parallel alignment of Ga or Ge tetrahedron groups along the c-aix. The ultraviolet transmittance spectrum signifies the brief-wavelength absorption edges of BaGa2GeS6 and BaGa2GeSe6 are 380 nm and 440 nm, respectively.
We deliver large-purchase harmonics from crystalline solids using a tunable mid-IR OPA with fifty kHz repetition charge. Working with nonlinear self-compression in YAG crystals, we deliver sub 3-cycle pulses at 3.8 μm wavelength for prime harmonic spectroscopy. Read a lot more
The dislocations are traced via the repetition of etching from epitaxial layer on the interface. The effects demonstrate that dislocations during the substrates are envisioned to bend along the route regular for the epitaxial development path on the interface.
0 Summary Summary: BaGa4Se7 (BGSe) and BaGa2GeSe6 (BGGSe) crystals are novel infrared nonlinear optical supplies independently created by Chinese researchers. As a result of excellent extensive effectiveness and also the vital application worth in laser field, they've got captivated Significantly notice in your house and abroad.
As a result of excellent extensive general performance and also the crucial application price in laser field, they have got captivated A great deal notice at your home and abroad. The development of crystal advancement and laser output of BGSe and BGGSe are summarized, and the longer term progress is prospected.
ZnGa2Se4, a nonlinear product with large mid infrared transparency and superior thermomechanical Houses
Laser-induced damage threshold from the nonlinear crystals BaGa4Se7 and BaGa2GeSe6 at 2091 nm while in the nanosecond regime
24% and that is similar with a single obtained with high repetition level lower-Electrical power laser devices like in [9]. Taking into account a risk to raise pump pulse Power of our set up as much as ~ten mJ, the DFG pulse Power is often amplified as much as ~24 μJ at a similar efficiency, having said that, it necessary a large-aperture, ~fifteen mm in diameter BGGSe sample. Typical DFG pulse Strength in AGS wasn't confidently calculated with Ophir-3A power meter as a result of its lower signal.
The applicable Homes and conventions used for the freshly rising acentric monoclinic crystals belonging into the borate household are summarized and tabulated. The derivations are predicted to help build adherence to uniform nomenclature and conventions for these novel inorganic nonlinear crystals, and to do away with ambiguity and escalating confusion while in the literature and in the commercial specifications. The general expressions for your here productive nonlinearity are lessened for triclinic crystals of place team one to simplified types from the principal planes.
The best frequency conversion effectiveness of 10⁻⁴ was attained for a comparatively new PbIn6Te10 crystal, that is an get of magnitude bigger than former outcomes.
It truly is shown there are wavelength combinations at which the effective nonlinearity coefficient differs only a bit in a large frequency band.
The character of the instability and DFG energy lessen isn't distinct for us. One among the reasons can be linked by using a nonlinear absorption and plasma development, respectively, that triggers reflection/scattering/absorption on the longwave mid-IR pulse. The dependence of BGGSe transmittance on pump pulse Electrical power is introduced in Fig.
