Abstract: A method for combining power of separate directed energy beams each associated with a separate firing unit, on a common spot on target. The firing units are coordination and synchronization unit (FUSU) tracks a target and assigns a master firing unit and slave firing units. The master firing unit sends a guide beam to the target, forming a local coordinate system on said target, while the slave firing units track the target and track at least one spot of EM (electromagnetic) radiation on the target. The slave units calculate a direction vector, and fire a power beam at the target, together with the master unit.

Abstract: A method of ablating a material, the method comprising: (a) generating a beam of laser radiation in a form of plurality of pulses, the laser radiation having a wavelength suitable for ablating the material; and (b) within a duration of a pulse of the plurality of pulses, scanning the material by the beam, so as to transfer a predetermined amount of energy to each one of a plurality of locations of the material, the predetermined amount of energy being selected so as to ablate the material.
