Abstract
A laser irradiation apparatus which is provided with: an environment isolation container, which houses a laser oscillator and is disposed in water; a laser irradiation head, which collects laser beams and irradiates a part to be machined with the laser beams; a light guide section which transmits the laser beams from the laser oscillator to the laser irradiation head; a power supply apparatus which supplies the laser oscillator with power; a cooling water supplying apparatus, which supplies the laser oscillator with cooling water through a cooling water supplying path; and a temperature sensor which measures the temperature inside of the environment isolation container. The temperature and/or the flow quantity of the cooling water to be supplied from the cooling water supplying apparatus is controlled on the basis of the measurement results obtained from the temperature sensor.
