We present an erbium doped fibre laser (EDFL) in a MOPA (master oscillator power amplifier) configuration with intensity and frequency noise reduction using electronic feedback techniques. The intensity noise is suppressed using feedback to the pump diode current and the frequency noise is suppressed by locking the laser emission to a fibre interferometer and applying a feedback signal through laser cavity strain using a piezo-electric element.
