摘要:In one embodiment of the present invention, a long-life nitride semiconductorlaser element is disclosed wherein voltage characteristics do not deteriorate even whenthe element is driven at high current density. Specifically disclosed is a nitride

semiconductor laser element which includes a p-type nitride semiconductor and a p-sideelectrode formed on the p-type nitride semiconductor. In at least one embodiment, thep-side electrode has a first layer which is in direct contact with the p-type nitridesemiconductor and a conductive second layer formed on the first layer, and the secondlayer contains a metal element selected from the group consisting of Ti, Zr, Hf, W, Moand Nb, and an oxygen element.
