Abstract

We report a new pulsed, narrow linewidth, single-mode, polarization maintaining (PM) all-fiber laser source in master oscillator and power amplifier (MOPA) configuration that can operate over the C-band. The single-frequency pulsed fiber laser seed was achieved by actively Q-switching a fiber laser using a piezo, with a wide pulse duration tuning range of 7.5 ns - 1.24 μs. We use single-mode PM large core highly Er/Yb co-doped phosphate glass fiber (LC-EYPhF) in the power amplifier stage of MOPA to achieve 54 μJ/pulse for 153-ns pulses at 1538 nm with repetition rate of 20 kHz and an estimated linewidth of ~ 5 MHz.
