摘要： A fiber laser of an MOPA type includes an MO which is a laser oscillator for generating seed light, a PA which is a light amplifier connected to a rear stage of the MO, for amplifying and outputting laser light emitted from the MO, and a reflection device which is provided between the MO and the PA. According to the present invention, the MOPA type fiber laser can decrease the peak value of the pulse which is emitted toward the MO or the pump light source by self-oscillation or reflection, and makes it unlikely that the pump light source or the MO will be damaged.
