This paper discussed beam parameters of the laser diode array and its beam quality. By using a high resolution CCD array the intensity profiles of the laser diode array were measured and the beam width, far field divergence, beam parameter product and Μ :-factor were obtained. By calculating the intensity moments the relation between beam parameters of the laser diode linear array and its structure was found, and the method for improving beam properties of laser diode arrays was discussed.
