To exclude disadvantages of a laser aiming device at an existing technological level and to provide a necessary condition which is used to generate a partial beam in different colors, without spoiling the intensity of light.
A laser array 21 is constituted, so as to be installed in a multilaser aiming device. A light source, which generates at least one primary laser beam and a spectroscope 7 which comprises reflecting faces 20, are provided at the aiming device. By the spectroscope, at least one primary laser beam can be split into at least two partial beams which are extended mutually perpendicular. The light source is provided with two semiconductor lasers 22, 23, and their light-emitting faces are provided with sizes in the longitudinal direction and sizes in the transverse direction, The ratio of the sizes is set at about 2.5:1 to about 4:1. When the semiconductor lasers 22, 23 which are provided with the light-emitting faces are arranged properly, the sizes 1 in the longitudinal direction on the light emitting faces are turned mutually by 90°, so as to be extended, and primary beams P, Q which are generated from both semiconductor lasers 22, 23 can be composed at the front or the side of a spectroscope 24.
