摘要

在高功率掺铒全光纤激光器的正啁啾脉冲泵浦下，在25 atm的压力下，在充满甲烷的空心芯转轮光纤中，证明了单级联1.56到2.84 μm的SRS转换。在最大泵浦脉冲能量为34 μJ(平均功率3.74 W)、脉冲持续时间约260 ps的情况下，在中心波长2.84 μm处可产生持续时间为110 ps、能量为1.33 μJ(平均功率133 mW)的超短脉冲。基于高功率光纤源泵浦的空心光纤的气体光纤拉曼激光器有望产生在中红外范围内发射USPs的全光纤系统。

1.56-to-2.84 μm SRS conversion of chirped pulses of a high-power erbium fibre laser in a methane-filled hollow-core revolver fibre

Single-cascade 1.56-to-2.84 μm SRS conversion is demonstrated in a hollow-core revolver fibre filled with methane at a pressure of 25 atm under pumping by positively chirped pulses of a high-power erbium-doped all-fibre laser. At a maximum pump pulse energy of 34 μJ (average power 3.74 W) and a pump pulse duration of about 260 ps, ultrashort pulses (USPs) with a duration of 110 ps and an energy of 1.33 μJ (average power 133 mW) are achieved at the centre wavelength of 2.84 μm. The gas fibre Raman lasers based on hollow-core fibres with pumping by high-power fibre sources are promising for producing all-fibre systems emitting USPs in the mid-IR range.
