abstract = "Due to the development of a new 6G data transmission range, it is urgent to search for new materials for the creation of integrated devices capable of operating in the frequency range of 140350 GHz (sub-terahertz range). One of the promising materials for this range is the GaSe crystal due to its exceptional properties, represented by transparency in the telecommunications (1.5 mkm) and sub-terahertz ranges and a high nonlinear optical coefficient. Despite many works aimed at studying the properties of doped and undoped gallium selenide crystals, relatively few studies have examined the coefficient of nonlinear susceptibility of crystals in their undoped state; no such studies have been discovered for doped crystals. This paper presents an estimation of the second-order nonlinearity χ(2) of GaSe(1-x)Sx crystals, where x takes the values 0, 0.03, 0.12, 0.16, and 0.22. The estimation was made on the basis of previously obtained data on the value of the electro-optical coefficient r22 for GaSe(1-x)Sx crystals. Due to the use of several approaches to estimate the second-order nonlinear susceptibility coefficient and based on the data of other authors on the study of GaSe crystals in the terahertz range, calculations and comparisons of the results were performed. The discrepancy between the values of χ(2) from 5 to 28 pm/V, depending on the experimental conditions, is shown. For the first time, second-order nonlinearity was estimated for GaSe crystals with varying degrees of sulfur doping.
