1. A laser system comprising:

  • (a) a laser emitting nonvisible radiation optically connected to a first optical fiber, such that a nonvisible laser beam is transmitted through the optical fiber;

    (b) at least one visible light source optically connected to a plurality of second optical fibers, such that a visible light beam is transmitted through each of the plurality of second optical fibers, constituting a plurality of visible light beams;

    (c) collimating optics, constituting collimating means for collimating the nonvisible laser beam and the plurality of visible light beams, such than the plurality of visible light beams are in focus at a distance from the output of the collimating optics, said distance being the distance at which the nonvisible laser beam has an optimum power density; and

    (d) an optical fiber connector that connects the first optical fiber and the second optical fibers to the collimating optics, and that positions the first optical fiber at the center of the plurality of second optical fibers, such that the plurality of visible light beams surround and identify the position of the nonvisible laser beam.
