Abstract
A 2D study in focus point of two identical femtosecond laser sources introducing a temporal displacement for ultra-short pulses generation based on Coherent Beam Combining was developed. This study is based on numerical simulation which shows the spatial and temporal properties of the electromagnetic field. The piston error is introduced by moving one of these two laser sources in the same direction, while the other laser source is fixed. The interval considered for the laser source displacement (piston error) is between lambda/10 and 40 lambda. The results are relevant for the coherent beam combination at the Extreme Light Infrastructure facility.
