摘要	A semiconductor laser module is provided to obtain a high optical output power, prevent kinks in the current - optical output power characteristic, and emit laser light of a narrow spectrum width. Also provided is a pumping light source apparatus which wavelength multiplexes the laser light to obtain a high optical output power. The semiconductor laser module comprises a Fabry-Perot semiconductor laser device with a cavity of 1800 mu m or more in length and a fiber grating optically coupled to the semiconductor laser device. The reflection bandwidth of the fiber grating is 3nm or less and is greater than the wavelength interval of longitudinal modes of lasing light from the semiconductor device.
