Abstract:
1. A high-energy laser system intercepting a target, comprising: a laser oscillator which generates a laser beam to be irradiated to the target; a light amplifier which receives the laser beam irradiated to and reflected by the target so as to amplify the laser beam; a phase conjugate mirror which reflects the laser beam amplified by the light amplifier, wherein the laser beam that is reflected by the phase conjugate mirror is amplified again in the light amplifier, and then irradiated to the target so as to intercept the target; an n-th order harmonic generator which is disposed between the light amplifier and the target so as to convert the frequency of the reflected and amplified laser beam; and a wedge-shaped glass plate which is disposed at a front side of the n-th order harmonic generator so as to change an optical path of the laser beam, wherein the optical path of the laser beam is changed in the wedge-shaped glass plate by controlling a value n of the n-th order harmonic generator and an angle β of the wedge-shaped glass plate, thereby intercepting the target.
