All-normal-dispersion dissipative soliton Yb fiber laser

Abstract

An all-fiber ytterbium-doped laser based on nonlinear polarization rotation (NPR) without dispersion compensation and additional filter has been demonstrated. The formation of the dissipative soliton pulse is a self-consistent result of various effects in the laser cavity. Stable mode-locked pulses with pulse energy of 1.1 nJ have been achieved.
