利用色散位移保偏光纤和飞秒光纤激光器，实现了波长在1.32-1.75 μm范围内的宽波长可调谐超短脉冲的产生。同时产生了清晰的sech 2孤子脉冲和反斯托克斯脉冲。通过改变光纤的输入功率，两个脉冲的波长向相反的波长侧移动。孤子脉冲的最大转换效率为65%，反斯托克斯脉冲的最大转换效率为10%。孤子脉冲和反斯托克斯脉冲沿光纤沿着共同传播。讨论了反斯托克斯脉冲波长漂移的机理。
Using dispersion shifted polarization maintaining optical fibers and a femtosecond fiber laser, a compact system of widely wavelength tunable ultrashort pulse generation is demonstrated in the wavelength region of 1.32–1.75 µm. The clear sech2 soliton pulse and the anti-Stokes pulse are generated simultaneously. The wavelengths of the two pulses are shifted to the opposite wavelength sides by changing the fiber input power. The maximum conversion efficiencies are as large as 65% for the soliton pulse and 10% for the anti-Stokes pulse. The soliton pulse and the anti-Stokes pulse copropagate along the fiber. The mechanism of the wavelength shift of the anti-Stokes pulse is also discussed.
