In the case of a one-dimensional laser array (100) the emerging light beam (5) from each laser-active stripe (1) is refracted through a deflection angle (901) which is equal to the wavelength (201) divided by the mean separation (101) between two stripes (1) having the same phase angle (10). In this case, the outlet surface (25) of each stripe (1) is tilted (20) through a tilt angle (21) which is equal to the refraction angle (901) divided by the refracted index of the optical material of the laser-active stripe (1). <IMAGE>
