摘　　要：A novel organized multipulse pattern and its birth dynamics under strong optomechanical effect in microfiber-assisted ultrafast fiber laser are investigated in this work.The background pulses are observed to obviously exhibit selectively amplifying self-organized process of evolving into quasi-stable equidistant clusters.The radio frequency spectrum of the multipulse pattern displays a harmonic mode-locking-like behavior with a repetition rate of 2.0138 GHz,corresponding to the frequency of torsional-radial(TR_(2m))acoustic mode in microfiber.The results show the evidence of optomechanical effect in dominating the birth dynamics and pattern of multipulse.
