摘要

A number of acousto-optic figures of merit and elasto-optic constants of a mercury bromide (Hg2Br2) crystal were measured. The key characteristics of the wide-angular acousto-optic tunable filter based on a Hg2Br2 crystal in the (110) planewere calculated from the measurements carried out and previously known data. It is demonstrated that the crystal makes it possible to create effective devices operating in the 5-25 mu m wavelength range. In addition, we proposed the design of a filter operating in the long-wavelength infrared range of 8-12 mu m, providing spectral resolution up to R = 300 and a field of view outside the crystal up to 10 degrees. Its diffraction efficiency can reach up to 2% per 1W of continuous driving power. (C) 2021 Optical Society of America
