摘　　要：在光纤-光栅对激光脉冲压缩中,由于受激喇曼散射和自相位调制的竞争,使得泵浦激光脉冲波形重整,且自相位调制谱极不对称。本文用2m的单模保偏光纤,在产生较强的受激喇曼散射的情况下,得到较为对称的泵浦激光的自相位调制功率谱,并讨论了自相位调制功率谱的一些特点。The shape of pumping laser pulse was reshaped in fiber-garting compression of optical pulse due to the competing between self-phase-modulated and stimulated raman scattering. The salf-phase-modulated power spectra was very asymmtric. We obtained some symmtric spectra produced by salf-phase-modulated in our experiments using a 2 m single-mode polarization-preserving silicon fiber. Some characteristics of Self-Phase-Modulated power spectra are discussed.
