The low-energy laser beam has a divergence angle not substantially greater than that of the working laser beam and includes sections on opposite sides of and equally spaced from the center of the working laser beam such that the focal point of the sections of the low-energy laser beam, when focussed to a single point by the focussing lens, also designates the focal point of the working laser beam. | |
