Synchronization of femtosecond laser with nanosecond (~250 ns) laser results in a large enhancement in laser ablation efficiency of the Si wafer 12 times more than that with an independent laser exposure. Transient changes in the status of target material due to the proceeding nanosecond laser increase the femtosecond laser ablation efficiency.
