Embodiments of the present invention describe systems and methods for delivering ultrashort laser pulses through an optical fiber system with higher order mode fiber output and without pre-chirping. In one embodiment of the present invention, an all-fiber delivery system comprises a mode-locked solid-state or fiber laser for generating laser pulses in the 0.2 μm to 1.3 μm wavelength range, a single mode fiber with normal dispersion, and a long-period-grating mode converter, and a higher order mode fiber with anomalous dispersion, wherein the all-fiber delivery system is free of bulk optics, and propagates laser pulses without pulse pre-chirping, and wherein higher order mode output beam from the all-fiber delivery system comprises pulses at less than about 200 femtoseconds.
