报道了基于空芯光纤中气体受激拉曼散射效应的1.5 μm波段光纤激光实验。利用高峰值功率、窄线宽、亚纳秒量级的1064 nm微芯激光抽运一段充高压乙烷气体的空芯光纤。通过乙烷气体分子的受激拉曼散射，获得了1553 nm的激光输出，峰值功率达到16.6 kW，线宽小于0.2 nm，脉宽约为435 ps。该功率水平是目前在掺铒光纤中获得的最高峰值功率的4倍以上。该研究为同时实现高峰值功率和窄线宽的1.5 μm波段光纤激光提供了一条新的技术途径。

A 1.5 μm fiber laser generation experiment in gas-filled hollow-core fiber by stimulated Raman scattering is reported. A high pressure ethane-filled hollow-core fiber is pumped with a high peak-power, narrow linewidth, subnanosecond pulsed 1064 nm microchip laser. The 1553 nm pulse with peak power of 16.6 kW is generated via stimulated Raman scattering of ethane. The linewidth is less than 0.2 nm and the pulse duration is about 435 ps. To the best of our knowledge, the peak power obtained here is more than four times of the highest value reported for erbium-doped fibers. The study provides a technical pathway for 1.5 μm fiber laser with both high peak-power and narrow linewidth.
