1. A medical and surgical laser probe for contact laser surgery;

  • the probe optically connected to a laser source through an optical laser guide means;

    which probe is characterized in that the probe is made of an optically transparent solid material and comprised of a laser beam receiving portion and a tapered portion having a laser beam emitting tip end face;

    the tapered portion defining cross-sections of generally circular form having no surgical cutting edges along the tapered length thereof, and the length and the taper angle of the tapered portion and the radius of the tip end face of the tapered portion are determined and structural so that substantially all laser beam incident on the laser beam receiving portion from the laser beam guide means is emitted from the tip end face of the tapered portion without leaking out from the tapered face of the tapered portion;

    the laser beam being concentrated at the tip end face whereby said concentrated laser beam facilitates the surgical cutting of tissue.
