摘要： When an output instruction is input to the control unit, the control unit controls the seed laser light source and the pumping light source to be either in a pre-pumped state or in an output state. In the pre-pumped state, laser light is not output from the seed laser light source, and pumping light with a predetermined intensity based on a laser light intensity set by the output setting unit is output from the pumping light source for a certain period of time. In the output state, laser light is output from the seed laser light source, and pumping light is output from the pumping light source, so that laser light with the intensity set by the output setting unit is output.

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.
