摘要
研制了基于光纤Bragg光栅的掺铒单模光纤激光器。用 980nmLD作抽运源 ,在 1 56 μm波段获得了谱线宽为 0 1nm的激光输出。最大输出光功率为 1 73mW。输出功率稳定性为± 0 .0 2dB ,波长稳定性为 0 0 5dB。阈值抽运光功率为 7mW ,斜率效率为 3%。
By using Er 3+ doped fiber, a single mode fiber laser based on fiber Bragg grating was developed. When it was pumped by 980 nm laser diode, the output spectral bandwidth was measured as 0.1 nm at 1.56 μm. The max. output power was measured as 1.73 mW. The power stability is better than ±0 02 dB, and the stability of output wavelength is better than 0.05 dB. The laser had a threshold of 7 mW and a slope efficiency of 3%.
