We demonstrate propagation of femtosecond pulses through a large-mode-area, higher-order-mode (HOM) fiber with an effective area of . The pulses propagate stably in the mode of the fiber through lengths as long as . The strongly chirped pulses exiting the amplifier fiber are dechirped by the high-order-mode fiber, resulting in pulses with a peak power of after propagation in of the positive-dispersion fiber. A small amount of self-phase modulation is observed in the compressed pulses and is described well by a nonlinear Schrödinger equation model that takes into account the measured effective area and dispersion of the HOM fiber.
