  • Multi-resonator switching laser
    Patent number: 4660205
    Abstract: A laser comprises a laser medium and multiple resonators, together with means for switching coherent radiation from one resonator to another. If one of the resonators includes appropriate loss means, the laser can be self injection-locked and provide high-power, single-longitudinal mode radiation. Another embodiment of the laser provides successive laser pulses, separated by a short time interval and having different characteristics. A phase conjugate laser and an improved ring laser are also provided.
