Paper Abstract

We demonstrate a low-repetition-rate mode-locked figure-of-9 erbium-doped fiber laser at a center wavelength of 1550 nm by using an all-polarization-maintaining (PM) nonlinear amplifying loop mirror (NALM) configuration. This laser can generate Gaussian-shape noise-like pulses (NLPs) at a repetition rate of 2.15 MHz with a radio-frequency (RF) signal-to-noise ratio of greater than 50 dB and can be self-started mode-locked with a pulse energy of 11.68 nJ. The fluctuation of the average output power in 60 hours is 1.27% root mean square (RMS), which proves its high power stability. To our knowledge, this is the first report of an all-PM NALM erbium-doped fiber laser generating NLPs at the center wavelength of 1550 nm.
