摘　　要：利用环形腔结构在L波段获得了 43nm(15 6 7.1nm～ 16 10 .1nm)范围的宽带连续可调谐激光输出。由于同时采用了高浓度掺铒光纤和 1480nm激光二极管 (LD)抽运源 ,极大地降低了激光器的抽运阈值 ,提高了斜率效率和输出功率。在整个可调范围内 ,激光器的输出功率达 10 .9dBm～ 12 .1dBm(95mW抽运 ) ,信噪比高于 6 0dB ,在 15 85nm的斜率效率为 0 .2 0 1。Efficient L-band (long wavelength band) fiber ring laser with tunable range of 43 nm (1567.1 nm～1610.1 nm) is demonstrated. Both high concentration Erbium-doped fiber and 1480 nm pump laser diode (LD) were used to depress the laser threshold pump power and to increase the slope efficiency. Output powers between 10.9 dBm and 12.1 dBm were achieved when 95 mW pump power was provided. And the signal-to-noise radio was better than 60 dB. A high slope efficiency of 0.201 was obtained at lasing wavelength of 1585 nm.
