Abstract

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