Abstract

A diode array pumped Nd3+-doped superfluorescent fibre source with 320 mW output power and a 4–6 nm FWHM bandwidth centred at 1058 μm is reported. The device is prevented from lasing off reflected light from Rayleigh backscatter by seeding an Nd3+-doped fibre amplifier with a primary superfluorescent source of moderate power.
