• A technique for generation of a structurally stable hyperbolic beam using Fourier transform holography is reported. Bessel function with their arguments having hyperbolic locus is used for generating a diffractive optical element (DOE). For the introduction of optical vortex a circular vortex term is used. However, it is also possible to generate such beams without any optical vortex term. Both the techniques have their own advantages. The resultant DOE is illuminated with a collimated beam and proper filtering of its Fourier transform generates the expected hyperbolic beam. The resultant beam keeps its shape unchanged up to ${\sim}45$ cm.
