Abstract
When an output instruction is input to a control unit, the control unit controls a seed laser light source and a pumping light source to be either in a pre-pumped state or in an output state. In the pre-pumped state, the pumping light source outputs, for a predetermined period, pumping light with an intensity determined based on the duration of the period of time from when the output state prior to the input of the output instruction to the control unit comes to an end till when the output instruction is input to the control unit. In the output state, to cause the output unit to output laser light, the seed laser light source outputs laser light, and the pumping light source outputs pumping light.
