  • High-energy laser system intercepting a target and method thereof
    Patent number: 9074853
    Abstract: A high-energy laser system intercepting a target using a phase conjugate mirror includes a laser oscillator which generates a laser beam irradiated to the target, a light amplifier which receives the laser beam irradiated to and reflected by the target so as to amplify it, a phase conjugate mirror which reflects the amplified laser beam. And 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.
    Type: Grant
    Filed: September 10, 2010
    Date of Patent: July 7, 2015
    Assignee: KOREA ADVANCED INSTITUTE OF SCIENCE AND TECHNOLOGY
    Inventors: Hong Jin Kong, Jae Sung Shin, Sang Woo Park, Kang Sup Shim, Seong Woo Cha
