1. A hand-held laser apparatus comprising:

  • a laser diode that is adapted to produce a monochromatic laser beam;

    a front lens adapted to receive the beam directly from the laser diode and exploit the natural beam divergence of the laser diode to form an substantially coherent monochromatic, collimated output beam;

    wherein the formed beam defines on a plane perpendicular to the direction of propagation of the beam an elongated illuminated area in which the length of the illuminated area is at least twice the size of the width of the illuminated area;

    a controller that is adapted to control activation of the laser diode; and

    an encasement enclosing the laser diode, the lens and the controller;

    wherein the encasement is adapted to be hand-held, and the optical-mechanical configuration of the apparatus allows a changing of the front lens and thus of the effective aperture and radiant intensity of the output beam.
