To explore the structural, vibrational, and thermodynamic Homes in the chalcopyrite-style compound AgGaS2 stressed, we utilized hydrostatic pressure towards the comfortable compound based on the initial concepts calculation and quasi-harmonic approximation. The structural parameters, including lattice constants and bond lengths lessen monotonically Along with the increasing stress. The phonon dispersion curves less than different pressures expose the structural stage transition of chalcopyrite-kind compound AgGaS2 at about four GPa. The intrinsic system of thermal conductivity for your chalcopyrite-sort compound AgGaS2 has been shown with phonon anharmonicity. The frequencies of the optical phonons at the middle issue Γ of the very first Brillouin zone were being calculated Together with the longitudinal optical–transverse optical (LO–TO) splitting manner.
Silver Thiogallate (AgGaS2, AGS) has become shown as an effective crystal for nonlinear parametric interactions in the infrared spectral variety. Its transparency region ranges from 0,fifty three to twelve µm. AGS based mostly optical parametric oscillators function constantly tunable radiation about a wide array of wavelengths while in the infrared spectral selection. Substantial transparency inside the quick wavelength variety beginning at 550 nm is Employed in OPOs pumped by Nd:YAG laser.
Slender AgGaS2(AGS) crystal plates are preferred at ultrashort pulse generation in mid IR range by distinction frequency generation using NIR wavelength pulses.
As regular illustrations, two ternary compounds, AgGaS2 and LiAsSe2 crystals are thought of, and besides the composition observed experimentally, the geometries and optical performances of other metastable (or more secure) phases have been explored. Our success Evidently display the current technique can provide a possible solution to structure and enhance new inorganic NLO crystals.
LiInS2 is pyroelectric too, its electro-optical parameters are the base for utilizing it as a powerful electro-optical material. A few‐frequency collinear AgGaS2 Crystal stage matching is possible in LiInS2, LiInS2 has big birefringence and lower absorption inside the THz frequency area is judged to generally be a most likely extra beneficial optical nonlinear content when compared to the analogous compound LiGaO2.
What is the performance range of up-conversion of CO2 laser radiation graphic into in close proximity to-IR or seen region making use of AgGaS2 crystal? Up-conversion of CO2 laser radiation graphic into in the vicinity of-IR or visible region working with AgGaS2 crystal has an performance approximately thirty%.
Silver thiogallate, AgGaS2, is really a consultant member with the AIBIIIC 2VI spouse and children with chalcopyrite structure. AgGaS2 is strongly piezoelectric and it is period matchable for 2nd harmonic era. The lattice constants of the tetragonal crystal absolutely are a

Bismuth Triborate (BiB3O6 or BIBO) is a recently produced nonlinear optical crystal. It possesses significant successful nonlinear coefficient, high injury threshold and inertness with respect to humidity.
These info permitted us to refine the Sellmeier equations of the a few principal refractive indices. These equations are legitimate in excess of the complete transparency ... [Clearly show entire abstract] range of GdCOB then might be utilized to compute the tuning curves of infrared optical parametric generation.
BaGa2GeSe6 (BGGSe crystal for short) belongs to R3 space group of tripartite process, which has large laser hurt threshold, broad transmission vary (0.5~18μm), moderate birefringence, big nonlinear coefficient, stable chemical Attributes, large crystal symmetry and simple processing. Nd:YAG laser may be used for pumping, and it has essential software potential in frequency conversion of infrared lasers including frequency doubling of CO and CO2 lasers and era of mid-considerably infrared lasers by optical parametric oscillation.
