The wavelength and intensity of 980 nm diode lasers are stabilised by coupling the lasers to low-reflectivity (<5%) fibre Bragg gratings. Power of up to 100 mW from the singlemode fibre has been obtained. The increased stability of these permanently mounted devices may result in improved performance of erbium-doped fibre amplifiers.
