We present an experimental way how to produce extremely narrow polymer fibers using photopolymerization. Such fibers solidify in the high intensity regions of nondiffracting zero-order Bessel beam from the solution of UV cured resin. Bessel Beams are particularly suitable for this purpose because of their narrow high intensity core and long axial region of uniform intensity. The width of the created polymer fiber is strongly dependent on the properties of the Bessel beam, used laser power and
