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。

Silver Thiogallate (AgGaS2, AGS) has been demonstrated as an economical crystal for nonlinear parametric interactions inside the infrared spectral vary. Its transparency region ranges from 0,53 to 12 µm. AGS based optical parametric oscillators attribute continuously tunable radiation above a wide range of wavelengths during the infrared spectral array. High transparency while in the small wavelength array beginning at 550 nm is Employed in OPOs pumped by Nd:YAG laser.

In the nonlinear optical crystal, BBO crystal is really a sort of crystal with clear comprehensive benefits and excellent overall performance. It's an exceedingly wide gentle transmission selection, a big matching angle, a higher resistance to light hurt threshold, in addition to a broadband temperature matching. Fantastic optical uniformity, specifically for the triple frequency of Nd:YAG lasers.

six μm using plasma oscillations concept of solids. The calculated values are as opposed Using the experimental values as well as values noted by diverse personnel. Reasonably excellent arrangement has become found in between them.

The mechanical, thermal and optical Homes of newly predicted tetragonal NaGaS2 are described by 1st-principle DFT calculations. So that you can confirm the reliability of your calculation strategy, we also calculated these properties of AgGaS2. The attained values of AgGaS2 are in fantastic accord with the existing experimental and theoretical info. The Assessment on the elastic constants and modulus, anisotropy factors along with the linear compressibilities indicates NaGaS2 crystal, obtaining the secure mechanical construction, are definitely the anisotropic materials, and its capacity to resist the compression is stronger than the shape adjust.

All these knowledge authorized us to refine the Sellmeier equations of the 3 principal refractive indices. These equations are legitimate around the complete transparency ... [Exhibit comprehensive summary] range of more info GdCOB after which may very well be utilized to calculate the tuning curves of infrared optical parametric generation.

A specialized genetic algorithm solution in combination with very first-rules calculations is used to predict the stable structures of AgGaS2 crystal at distinct pressures. The outcomes exhibit the chalcopyrite construction to start with transforms on the monoclinic Cc section, and after that to some centrosymmetric framework that the next-harmonic generation (SHG) response of AgGaS2 is disappeared.
