A scheme of broadband spectrum Bessel beams directly output from a nonlinear photonic crystal fiber is designed. A femtosecond laser beam from a nonlinear polarization evolution laser system is directly coupled into a nonlinear photonic crystal fiber that is collapsed 1 mm by a fiber fusion splicer to enable the direct generation of broadband spectrum Bessel beams due to the modes coupling and coherent superposition at the collapsed district. The system operation can be achieved by all fiber without any other discrete devices. The broadband spectrum Bessel beams directly output from photonic crystal fiber have diffraction-free propagation in meter-scaled free space and are proved to have the characteristics of diffraction-free and selfheal in all spectrum.
