PROBLEM TO BE SOLVED: To provide a light source device that can vary the spectral form of SC (super continuum) light to be emitted. SOLUTION: A light source device 1a is equipped with a pulse light source 2 that emits an optical pulse train P1 of ultrashort pulse light having a pulse width of several femtoseconds, an optical fiber 11 optically coupled with the pulse light source 2 and receiving the light pulse train P1 to emit SC light P2, and an optical axis adjusting unit 3 optically coupled between the pulse light source 2 and the optical fiber 11. The optical axis adjusting unit 3 varies the optical coupling efficiency between the pulse light source 2 and the optical fiber 11 by using misalignment of optical axes between the pulse light source 2 and the optical fiber 11, and thereby varies the maximum power in each pulse included in the pulse train P1. Thus, the spectral form of the SC light P2 can be preferably varied. COPYRIGHT: (C)2007,JPO&INPIT
