0.4  μJ, 7  kW ultrabroadband noise-like pulse direct generation from an all-fiber dumbbell-shaped laser

Abstract

We report the direct generation of 0.4 μJ, 7 kW ultrabroadband picosecond noise-like pulses from an Yb-doped all-fiber oscillator based on dual nonlinear optical loop mirrors (NOLMs). Under the highest pump power, the average power of the main output port reached 1.4 W, and the 3 dB spectral bandwidths reached 76 nm and 165 nm from the two output ports, respectively. The design of dual-NOLMs shows both exceptional compactness in construction and distinct flexibility on the engineering of the mode-locking behaviors. To the best of our knowledge, this is the first demonstration of a watt-level dual-NOLM-based fiber laser. Based on this laser, the pulse energy and peak power of picosecond noise-like pulse from an all-fiber oscillator have been elevated by an order of magnitude.
