레이저 가공용 광원은 제1 펄스광렬을 출사하는 레이저 발진부와, 제1 펄스광렬에 대해서, 분파, 복수의 광로에서의 전파, 및 합파를 실시함으로써, 복수의 제2 펄스광렬을 포함하는 제3 펄스광렬을 생성하는 제1 광생성부와, 제3 펄스광렬에 있어서, 복수의 제2 펄스광렬로부터 적어도 1개의 제2 펄스광렬을 선택함으로써, 적어도 1개의 제2 펄스광렬을 포함하는 제4 펄스광렬을 생성하는 제2 광생성부와, 제2 광생성부를 제어하는 제어부를 구비하고, 제어부는, 제3 펄스광렬에 있어서, 복수의 제2 펄스광렬로부터 적어도 1개의 제2 펄스광렬을 선택하기 위한 제어 신호를 제2 광생성부에 송신한다. A light source for laser processing, comprising: a laser oscillation unit that emits a first light pulse train; a first light generation unit in which the first light pulse train is demultiplexed, propagated through a plurality of optical paths, and multiplexed, thereby generating a third light pulse train including a plurality of second light pulse trains; a second light generation unit that selects at least one second light pulse train from among the plurality of second light pulse trains in the third light pulse train and thereby generating a fourth light pulse train including at least one second light pulse train; and a control unit that controls the second light generation unit. The control unit transmits, to the second light generation unit, a control signal for selecting at least one second light pulse train from among the plurality of second light pulse trains in the third light pulse train.
