AgGaS2(AGS) crystal is among the best nonlinear laser crystals Employed in the infrared Functioning band At this time. Due to its massive nonlinear coefficient, superior infrared transmittance, reduced optical absorption and scattering, and reduced wavefront distortion efficiency, its software within the infrared discipline has long been popularized Increasingly more.
它的独特性质可用于研究各种现象和开发新技术，使其成为科学研究中的宝贵工具。
0 Summary Abstract: So that you can establish infrared imaging system determined by parametric up-conversion, according to the up-converter design that may transform ten.6 μm radiation into seen light-weight variety, the stage matching angle, walk off angle, satisfactory angle and efficient nonlinear coefficient of GaSe, ZnGeP2 and AgGaS2 crystals with diverse stage matching procedures ended up calculated.
Slim AgGaS2(AGS) crystal plates are common at ultrashort pulse era in mid IR vary by difference frequency technology employing NIR wavelength pulses.
As typical examples, two ternary compounds, AgGaS2 and LiAsSe2 crystals are regarded as, and Apart from the construction observed experimentally, the geometries and optical performances of other metastable (or even more steady) phases are already explored. Our final results Obviously exhibit the present technique can provide a possible technique to style and design and enhance new inorganic NLO crystals.
LiInS2 is pyroelectric as well, its electro-optical parameters are The bottom for applying it as an efficient electro-optical material. Three‐frequency collinear period matching can be done in LiInS2, LiInS2 has massive birefringence and reduced absorption within the THz frequency region is judged being a most likely much more practical optical nonlinear substance compared to analogous compound LiGaO2.
the infrared subject has been popularized a lot more and extra. At existing, this type of crystal is the best alternative for the frequency doubling substance of
Silver thiogallate, AgGaS2, is usually a agent member of your AIBIIIC 2VI family members with chalcopyrite construction. AgGaS2 is strongly piezoelectric which is section matchable for second harmonic generation. The lattice constants of this tetragonal crystal undoubtedly are a

six μm making use of plasma oscillations idea of solids. The calculated values are in contrast Using the experimental values as well as values noted by different employees. Reasonably great agreement has become uncovered involving them.
The mechanical, thermal and optical Attributes of newly predicted tetragonal NaGaS2 are claimed by to start with-theory DFT calculations. In an effort to establish the trustworthiness of the calculation strategy, we also calculated these Attributes of AgGaS2. The acquired values of AgGaS2 are in superior accord with the prevailing experimental and theoretical data. The Assessment in the elastic constants and modulus, anisotropy aspects along with the linear compressibilities implies NaGaS2 crystal, getting the steady mechanical construction, are classified as the anisotropic materials, and its capability to resist the compression is more powerful than the shape alter.
... It really is related to far more reasonable Bodily quantity of absorption cross part as α σ/N , where by σ is absorption cross area and N is particle density per unit volume.
BaGa2GeSe6 (BGGSe crystal click here for brief) belongs to R3 space team of tripartite method, that has higher laser destruction threshold, vast transmission vary (0.5~eighteenμm), moderate birefringence, substantial nonlinear coefficient, stable chemical Houses, higher crystal symmetry and simple processing. Nd:YAG laser can be used for pumping, and it's essential software potential in frequency conversion of infrared lasers for example frequency doubling of CO and CO2 lasers and technology of mid-far infrared lasers by optical parametric oscillation.
