Abstract

Delivery of high peak-power femtosecond pulses with fibers is constrained by nonlinear distortions accumulated during pulse propagation. We address this problem with a novel, to our knowledge, fiber schematic, where the pulse propagates in a small A eff ( 18 μ m 2 ) but highly dispersive (record value of 900 ps nm km ) medium, enabled by transmission in the LP 02 mode of a few-mode fiber. The novel fiber yields a low dispersion-to-nonlinear-length ratio (due to its large dispersion) despite its small A eff , hence enabling mitigation of nonlinearities. This enables fiber delivery of distortion-free < 150 fs , 1 nJ , and 840 nm pulses—an order-of-magnitude improvement over single-mode fibers of similar A eff .
