Airy beam forming device in the terahertz wavelength range

摘要

The utility model relates to the field of wave beam conversion and relates to devices that implement the method of forming self-bending Airy beams in the terahertz wavelength range. The utility model provides a simplification of the device for forming an Airy beam in the terahertz wavelength range, if possible, to quickly control the position and shape of the focus area. This task is achieved by the fact that in the device for generating a bending Airy beam in the terahertz wavelength range containing an electromagnetic radiation source, a phase mask, a diaphragm controlled by optical radiation is placed between the radiation source and the phase mask, forming a narrow radiation beam and located not symmetrically with respect to the optical axis of the device and the phase mask is made in the form of a cylindrical lens. 3 s.p. f-ly, 3 ill.
