Abstract

The proposed work analyzes the design features of the acousto-optical de?ector and ?lter on paratelurite. It is shown that under certain conditions the acousto-optical de?ector can be used as an acousto-optical ?lter (as an element that performs spectral ?ltering of the incident light beam). The fundamental possibility of creating a monochromatic light source with a variable wavelength and a spectrum width of about 5 nm using an acousto-optical de?ector as an element that adjusts the original wavelength is shown experimentally. As a broadband light source in this system, a semiconductor laser operating in subthreshold mode was used. The dependence of the output wavelength on the acoustic frequency is obtained. The comparison of experimental data with the calculated ones is given, it is shown that they have small di?erences.
