| 摘 要： | 在实验上对双包层光纤放大器进行了研究。采用新型内包层为六边形的铒镱共掺双包层光纤作为放大介质，用带尾纤的半导体激光器进行泵浦，对fs光脉冲进行放大。当用2.5 W的入纤功率泵浦50 cm长的双包层铒镱光纤时，把平均功率为10.8 mW、重复频率20.84 MHz的激光放大到176 mW，增益为12.2 dB，相应的单脉冲能量为8.1 nJ，放大后脉冲宽度为480 fs，峰值功率为16 kW。

| Abstract: | Experiment of the double-clad erbium-ytterbium co-doped fiber amplifiers were discussed. This fiber with hexagonal inner clad is utilized as gain medium to amplify femtosecond pulse, which is pumped by LD with pigtail fiber. The signal with 10.8 mW average power at 20.84 MHz repetition rate is amplified to 176 mW by using 50 cm long fiber when launched pumping power is 2.5 W. The gain is 12.2 dB and the single pulse energy is 8.1 nJ. The amplified pulse width is 480 fs, corresponding to a peak power of 16 kW. |
