Zusammenfassung:PROBLEM TO BE SOLVED: To provide a laser system capable of stably emitting harmonic light.SOLUTION: A laser system 100 comprises: a laser module 10 having a distributed feedback (DFB) laser 12 which oscillates laser light 24, a heater 14 which adjusts the temperature of the DFB laser 12, and a harmonic wave generation element 18 which converts the laser light 24 into harmonic light 34 of the laser light 24; and a control unit 40 which controls a heater current 28 inputted to the heater 14 so that an intensity of normalized harmonic light may be a predetermined intensity. The intensity of the normalized harmonic light is obtained by normalizing an intensity of the harmonic light 34, which is converted by the harmonic wave generation element 18, with an intensity of unconverted light 36, which passes through the harmonic wave generation element 18 without being converted into the harmonic light 34 by the harmonic wave generation element 18.
