Abstract: The present invention relates to a light source device and a measuring device which use a change in mode-locked resonated output light over time using a change in a cycle of an electrical signal corresponding to a change in the intensity of the output light according to a mode locking condition for each of different light paths in a resonator. The light source device includes an electrical signal generator configured to control the intensity of an optical signal from the light source device, and an optical gain unit controlled by periodic electrical signals having cycles calculated by dividing a round-trip time of photons corresponding to each of different light paths by an integer multiple. The intensity of the optical signal is controlled by the optical gain unit.
