Electron multiple recollision dynamics under intense mid-infrared laser fields is studied by means of the De Broglie-Bohm's framework of Bohmian mechanics. Bohmian trajectories contain all the information embedded in the time-dependent wave function. This makes the method suitable to investigate the coherent dynamic processes for which the phase information is crucial. In this study, the appearance of the sub-peaks in the high harmonic generation timefrequency profiles and the asymmetric fine structures in the above-threshold ionization spectrum are analyzed by the comprehensive and intuitive picture provided by Bohmian mechanics. The time evolution of the individual electron trajectories are closely studied to address some of the major structural features of the photoelectron angular distributions. I.
