| 摘 要： | 研究了液芯波导中受激拉曼散射和受激动力学散射的阈值随泵浦激光脉宽的变化，发现受激动力学散射的阈值随泵浦脉冲前沿增长率增大而下降。研究了受激动力学散射和受激拉曼散射的竞争，结果表明受激动力学散射可分解为两种成分，其中与瞬态泵浦功率密度增长率相关的成分在大于阈值的泵浦脉冲前沿处于竞争优势，与瞬态泵浦功率密度相关的成分在高泵浦功率密度处于竞争优势，并讨论了其相应的机制。

| Abstract: | Competition between stimulated dynamic light scattering (SDLS ) and stimulated Raman scattering (SRS) in CS2 liquid-core waveguide is studied by timeresolved pump pulse duration and pump density dependent experiments. It is found that the threshold of SDLS is dependent on the pump pulse duration. The competition between SDLS and SRS implies that SDLS consists of two contributions, one relates to the increasing rate of transient pump power density at the rise-time of pump pulse;the other relates to the transient pump power density, and dominates around the peak of high density pump pulse. Their mechanism is discussed. |
