Abstract
A laser maintenance apparatus including a laser system which includes an optical system for emitting, in a first irradiation condition, a generation laser beam for generating an ultrasonic wave in a portion of an object on which maintenance is to be performed, and including a laser source configured to generate and detect a detection laser beam which interacts with the ultrasonic wave generated by the laser light beam in the first condition. The laser maintenance apparatus also includes a light transmitting device for transmitting laser light emitted from the laser system, a laser irradiation device for irradiating laser light transmitted by the light transmitting device to the object portion, and a transporting/scanning mechanism for transporting the light transmitting device and the laser irradiation device to a portion near the object portion, and scanning over an arbitrary range at the object portion.
