N2 - In this study, the beam mode conversion in a nematic liquid crystal film deposited on the end-face of a single-mode optical fibre is considered. The infrared laser radiation delivered by this fibre induces a defect structure in the initially homeotropic liquid crystal. This leads to the formation of an output light beam with the annular intensity distribution in its cross-section. The obtained beam mode maintains its transverse profile in free space and can be interpreted as an optical vortex.
