| 英文摘要 | To achieve stable multimode output even when driven by a drive current near a threshold value, provided is a laser apparatus comprising a semiconductor laser element; a wavelength selecting element that performs laser oscillation by forming a resonator between itself and a reflective surface of the semiconductor laser element to output oscillated laser light; and an optical system that is optically coupled to an emission surface of the semiconductor laser element with a coupling efficiency η and inputs to the wavelength selecting element light output from the emission surface. The optical system causes a value that is correlated with a minimum light output within a linear light output region in which light output is linear with respect to an injection current injected to the semiconductor laser element to be less than this value occurring when the coupling efficiency η is at a maximum. |
