    摘要: The present invention relates to a broad area laser with high efficiency and small far-field divergence, as well as high output power.According to the invention, the active layer (10), the first contact (22) and the second contact (24) each have a width (W) larger than 10 μm, and there is also an anti-wave guiding layer (20) which is positioned laterally in relation to the active region enclosed between the contacts (22, 24), wherein the refractive index of the anti-wave guiding layer (20) is larger than the minimum refractive index of the cladding layers (14, 18), and wherein the minimum distance (dx) between the anti-wave guiding layer (20) and a projection of one of the contacts (24) on the plane of the anti-wave guiding layer (20) lies between 0 and 100 μm.
