Title: Semiconductor laser chip

Abstract: Semiconductor laser chip, whereby a laser-active semiconductor structure is arranged in an optical resonator. Two or more series-connected, laser-active pn-junctions whose forward directions are isodirected are introduced into one and the same resonator of the semiconductor laser chip. A respective pn-junction whose forward direction is opposite the forward direction of the laser-active pn-junctions is arranged between two laser-active pn-junctions.
