N2 - Ga50%Se(50-x)%Sx% crystals, where x has values 0, 1.5, 6, 8 and 11, were investigated as terahertz pulse detectors of at a laser wavelength of 1.55 μm. The optical and terahertz properties of the crystals, such as refractive indices, coherence lengths and electro-optical coefficients are measured. At the wavelength of laser radiation 1550 nm, it was demonstrated that the Ga50%Se44%S6% sample has the maximum detection efficiency. The detection efficiency was evaluated based on the maximum signal amplitude. It was shown that for pure GaSe electrooptic coefficient reff had a value of 0.975 pm/V, for the most efficient crystal Ga50%Se44%S6% reff = 1.262 pm/V. These results are in good correlation with other studies at another wavelengths. The studies were supported by the Ministry of Science and Higher Education of the Russian Federation, project #FSUS-2020-0029. The authors acknowledge core facilities “VTAN” (Novosibirsk State University) for the access to its experimental equipment.
