摘要
阐述了飞秒激光脉冲在随机介质传播过程中产生时域散斑的原理,并对时域飞秒散斑进行了测量.时域飞秒散斑的产生是飞秒脉冲在随机介质中经历多重散射形成的随机干涉现象在时域的体现.初步讨论了时域散斑的统计特性并给出了相应的实验结果.
Temporal femtosecond laser speckles are investigated both theoretically and experimentally. It is theoretically predicted that the temporal femtosecond speckles is generated when a coherent femtosecond pulse propagates through a random media. Temporal speckles on femtosecond scale are observed experimentally. These temporal femtosecond speckles are a direct result of random interference between scattered waves. Statistical characteristics of temporal speckles are discussed, and experimental results are presented.
