Abstract:
1. A light source apparatus comprising: a laser oscillator configured to emit pulsed light, the laser oscillator equipped with a first optical resonator and a plurality of second optical resonators, the plurality of second optical resonators being arranged in parallel to each other and including input portions respectively connected to the first optical resonator; a light multiplexing unit configured to multiplex the pulsed light emitted from an output portion of each second optical resonator; and a light source control unit configured to change a repetition frequency of the pulsed light, wherein the light source apparatus sweeps the wavelength of the pulsed light which is multiplexed by the light multiplexing unit, an optical member having refractive index dispersion and an optical amplification medium are disposed in each of the plurality of second optical resonators, and the optical amplification media of the plurality of second optical resonators are different from each other in maximum gain wavelength, wherein the light source control unit changes the repetition frequency of the pulsed light to cause the light source apparatus to sweep the wavelength of the emitted pulsed light.
