1. all solid state femto-second laser of kerr lens mode locking Yb:

  • YCOB of a diode pumping, it is characterized in that, all solid state femto-second laser of kerr lens mode locking Yb;

    YCOB of this diode pumping comprises;

    pumping source, optical coupled focusing system, the first concave mirror, Yb;

    YCOB gain medium, the second concave mirror, plane mirror, the first prism, the second prism, flat output mirror;

    Pumping source, for exporting pumping laser;

    Optical coupled focusing system, focuses on Yb;

    YCOB gain medium for the pumping laser that pumping source is produced;

    Gain medium Yb;

    YCOB, receives the pumping laser that sees through optical coupled focusing system and the first concave mirror, is used to form laser gain;

    The first concave mirror, receives the gain laser that Yb;

    YCOB gain medium produces, and forms confocal system with the second concave mirror;

    The second concave mirror, receives the gain laser that Yb;

    YCOB gain medium produces, and then reflexes to the first prism;

    The first prism, receives the laser of the second concave mirror reflection, and is transmitted to the second prism;

    The second prism, receives the laser of the first prism transmission, and is transmitted to flat output mirror;

    Flat output mirror, receives the laser of the second prism transmission, and transmission gain laser An Yuan road is returned;

    Through the second prism, the first prism, the second concave mirror, Yb;

    YCOB gain medium, then arrive the first concave mirror and reflexed to flat output mirror by the first concave mirror successively;

    Flat output mirror, passes through the kerr lens mode locking laser pulse of flat output mirror stable output after gain laser starting of oscillation.
