A laser source device includes an optical amplifier having an optical amplifying medium that is configured to amplify a seed beam when the seed beam and an exciting beam are entered, a seed beam source for emitting a laser beam as the seed beam, and an exciting beam source for emitting an exciting beam. The seed beam source emits a pulse beam as the seed beam during a predetermined principal irradiation period. The seed beam source emits a substantially continuous beam as the seed beam, having a smaller power than a peak power of the pulse beam during a supplemental irradiation period different from the principal irradiation period. The exciting beam source emits the exciting beam such that the power of the exciting beam is smaller during the supplemental irradiation period than the power of the exciting beam during the principal irradiation period. |
