Abstract
A method for directing a laser pulsed beam towards a selected area/surface of an object, comprising transmitting from a laser assembly that includes an optical transmitter module a pulsed laser beam having a first pulse duration and illuminating therewith an area/surface of the object, thereby obtaining a reflected pulsed laser beam, the reflected pulsed laser beam including a leading portion reflected from a first reflecting area/surface of the object which is the area of the object that defines the shortest optical path between the optical transmitter module, the object and an optical receiver module; receiving, in a second laser assembly that includes the optical receiver module, the reflected pulsed laser beam and converting it into an amplified phase conjugated pulsed beam of a second pulse duration, and transmitting from the second laser assembly the amplified phase conjugated pulsed beam and illuminating therewith on selected area/surface of the object.
