英文摘要	There is provided a semiconductor laser device implementing a single transverse mode oscillation in an oscillation wavelength of 780 nm band and also having high reliability and long life in high-output driving state, and an optical disk recording and reproducing apparatus with use of the semiconductor laser device. A multiple quantum well active layer 105 is composed of InGaAsP, and a first cladding layer 103, a second cladding layer 107, a third cladding layer 109, and a first current blocking layer 112 are structured from III-V group compound semiconductor containing only As as V group element. Inside the first current blocking layer 112, a hollow portion 130 is provided in the vicinity of and approximately parallel to the ridge stripe-shaped third cladding layer 109.
