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.
