英文摘要	A method of producing a semiconductor laser device, comprising depositing a first cladding layer, an active layer, and a second cladding layer successively, which three layers having heterojunctions each between neighboring two layers, said first and second cladding layers being made of mixed crystals of a semiconductor material composing the active layer and another semiconductor material containing aluminum, depositing a fourth thin semiconductor layer on the second cladding layer, said fourth layer being made of material not including aluminum, and having charge carriers of the same type with that of the second cladding layer, depositing a fifth semiconductor layer on said fourth layer, said fifth semiconductor layer having charge carriers of the type opposite to that of the second cladding layer, forming a stripe-like groove by etching in said fifth semiconductor layer down to said fourth semiconductor layer, and depositing a sixth semiconductor layer on said fifth semiconductor layer and on said groove, said sixth layer having charge carriers of the same type with that of the second cladding layer.
