ATGS, or ammonium dihydrogen arsenate, is a crystal material that belongs to the family of nonlinear optical crystals. ATGS is a single crystal material, which means that it is composed of a single crystal with a regular arrangement of atoms.
Single crystals like ATGS have a unique and ordered atomic structure, which gives them unique physical properties such as high optical transparency, mechanical hardness, and electrical conductivity. These properties make them useful in various applications, such as in electronic and optical devices, sensors, and as substrates for epitaxial growth of thin films.
In particular, ATGS has attracted interest due to its excellent properties for nonlinear optics. Nonlinear optical materials are materials that exhibit a nonlinear relationship between the input light and the output light. This means that the intensity, frequency, or polarization of the output light is different from that of the input light.
ATGS is a promising material for nonlinear optics due to its large nonlinear coefficient, wide transparency range, and high damage threshold. These properties make it suitable for use in various optical applications such as frequency conversion, parametric oscillation, and optical switching.
