Abstract
An optical processing apparatus, an optical processing method, and an optically-processed product production method. The optical processing apparatus and the optical processing method includes emitting a first process light to a focal point set inside an object to be processed, using a first light-emitting unit, and emitting a second process light during a period of time in which plasma or gas is generated inside the object to be processed, by the first process light, using a second light-emitting unit. The processed product production method includes emitting a first process light to a focal point set inside an object to be processed, using a first light-emitting unit, and emitting a second process light during a period in which plasma or gas is generated inside the object to be processed by the first process light, using a second light-emitting unit.
