Abstract
A diode-pumped, broadly tunable, single frequency erbium, doped fibre ring laser is reported. Tuning and single longitudinal mode selection are accomplished by use of two fibre Fabry-Perot etalons. The threshold for 1.48 mu m pumping is 8.8 mW and the slope efficiency is 11.5%. The laser can be tuned to wavelengths between 1.530 and 1.575 mu m and operates singlemode throughout this range. Its linewidth is measured at 1.56 mu m to be less than 5.5 kHz.
