Cv. Poulsen et M. Sejka, HIGHLY OPTIMIZED TUNABLE ER3-DOPED SINGLE LONGITUDINAL MODE FIBER RING LASER, EXPERIMENT AND MODEL(), IEEE photonics technology letters, 5(6), 1993, pp. 646-648
A CW tunable diode-pumped Er3+-doped fiber ring laser, pumped by diode
laser at wavelengths around 1480 nm, is investigated. Wavelength tuni
ng range of 42 nm, maximum slope efficiency of 48% and output power of
14.4 mW have been achieved. Single longitudinal mode lasing with a li
newidth of 6 kHz have been measured. A fast model of erbium-doped fibe
r laser is developed and used to optimise output parameters of the las
er.
