A light source device (10) wherein the high-temperature plasma state after the start of the lighting is maintained stably and the light emission can be maintained stably and a decrease of the lighting life cycle by means of a heating of the light emission tube (1) is suppressed comprises a light emission tube (1), in which a light emitting means is enclosed, and a pulsed laser oscillator part (2) emitting a pulsed laser beam towards said light emission tube (1), wherein a continuous-wave laser oscillator part is provided emitting a continuous-wave laser beam towards said light emission tube (1). |
