| 英文摘要 | A semiconductor laser module (1) comprising a laser element (2) having an emission surface (2a) of excitation radiation and a reflection surface (2b) opposed to the emission surface, and an optical feedback medium (3) in which the major part of optical power from the emission surface (2a) is returned to the semiconductor laser element (2) by coupling means (4) while a part of the power from the emission surface is output. The emission surface (2a) of the semiconductor laser element (2) is coated with a low-reflection multilayer (2c) with a reflectivity of 10?-4¿ % to 10 %. The low-reflection multilayer (2c) has a reflection spectrum characteristic curve that takes a maximum at the center frequency and minimums near both sides. |
