Abstract

A passively mode-locked femtosecond erbium-doped bidirectional fibre laser with low pump threshold using chemical vapor deposition grown graphene saturable absorbers is demonstrated. Two synchronised and counter propagating soliton output pulse trains with a repetition rate of ~10.38 MHz and pulse widths of 660 fs and 860 fs are obtained simultaneously from the fibre laser. Simultaneous mode-locking of the fibre laser has been realised with a threshold pump power of 56 mW from a single pump laser diode, indicating a ~62% reduction in pump threshold compared to previous results.
