High brightness, low coherence sources are required in a number of optical sensor applications, particularly the fibre-optic gyro. An efficient superfluorescent, neodymium-doped phosphate glass fibre source has been developed which fulfils this requirement. The fibre shows a high gain efficiency at 1.053µm of 1dB/mW pump power and this permits pumping with an 810nm single-stripe AlGaAs laser diode to obtain > 5mW CW output power at a wavelength of 1.053µm for only 45mW of pump power.
