1. A end-firing surgical laser arrangement, comprising:

  • an optical fiber having an end through which laser energy exits the fiber; and

    a quartz ferrule welded to the fiber,wherein an index of refraction of the quartz ferrule is approximately equal to that of the fiber to cause laser energy to disperse as it exits the fiber, increasing an angle over which the laser energy is directed, said fiber being sufficiently flexible to enable bending of the fiber tip in order to aim the fiber tip at a desired surface.
