    • PROBLEM TO BE SOLVED: To provide a semiconductor laser device which suppresses the occur rence of induced Brillouin scattering at an high power output. SOLUTION: By providing an absorption layer 12 having an energy gap close to energy indicated by an oscillation frequency, near a GRIN-SCH-MQW active layer 3, the life of a photon produced in the GRIN-SCH-MQW active layer 3 is shortened and a spectrum width per one mode is widened, resulting in an increase in threshold value at which induced Brillouin scattering occurs. Compared with a conventional semiconductor laser device, a spectrum peak can be lowered so as not to exceed the threshold value at which induced Brillouin scattering occurs even if the same optical intensity is obtained, thereby suppressing the occurrence of induced Brillouin scattering.
