▎ 摘　　要

A low pump threshold passively harmonic mode-locked fibre laser is demonstrated. The key component is a chemical vapour deposition grown graphene saturable absorber to enable higher order harmonic mode-locking (HML) of the fibre laser with good output noise characteristics. With a relatively low pump power of 100 mW, the fibre laser generates approximate to 1 ps soliton pulses at the 21st order of HML with 40 dB of super-mode noise suppression.
