  • Laser gain medium and laser oscillator using the same
    Patent number: 8259763
    Abstract: A laser gain medium includes an optical medium configured to transmit a laser beam and having an incident face, a first face, a second face opposing to the first face; and gain media configured to amplify the laser beam while reflecting the laser beam. At least one of the gain media is joined on a first face of the optical medium as a first face gain medium, and at least one of the remaining gain media is joined on a second face of the optical medium as a second face gain medium. The laser beam is incident into the optical medium, and is amplified by the first face gain medium and the second face gain medium while being alternately reflected by the first face gain medium and the second face gain medium.
