Er/Yb-doped fiber laser with a repetition rate of ultrashort pulses of 484 MHz.

Abstract

In this study, we present a demonstration of a short ring cavity passively mode-locked composite Er/Yb-doped fiber laser with a saturable absorber, which is based on aerosol-synthesized single-walled carbon nanotubes. We have achieved stable soliton generation with a main pulse repetition rate of 484 MHz at the output. The optical pulses had a duration of 1.6 picoseconds, and the average output power was 1.5 mW.
