【摘要】 本文报道了在准单模石英光纤中对于ps泵浦脉冲,研究了多级SRS脉冲、泵浦光脉冲的时间特性和光谱特性以及它们之间的时间分离。发现SRS转换效率很高(80％以上),并且SRS的产生位置距光纤输入端很近(1.5m),对于63m光纤,观察到几乎连续的9级SRS光谱更多还原

【Abstract】 The temporal and spectroscopic characteristics of multi-order SRS pulses, pumping pulse, and their temporal separation in quartz quasi-monomode optical fiber are reported for ps pumping pulses. High conversion efficiency (over 80%) of SRS is found experimentally at high pumping power,and the place for SRS generation is close to the input end of the optical fiber (1.5m). Almost continuous orders of SRS spectrum have been observed for a 63m long optical fiber.更多还原
