Abstract:
1. A hybrid laser processing apparatus comprising: an injection nozzle including an injection hole; liquid supplying means for supplying the relevant injection nozzle with high-pressure liquid; a laser oscillator oscillating a laser beam; and a condensing lens condensing the laser beam oscillated from the laser oscillator to inject the liquid supplied from the liquid supplying means in a shape of a liquid column from the injection holes to outside and to guide a laser beam to the liquid column with a condensing lens to carry out processing on the object to be processed, characterized in that, an inclined plane which reduces the diameter toward the object to be processed is formed at the entrance of the injection hole, the focus of the condensing lens is set inside the liquid column beyond a minimum diameter part of the inclined plane and closer to the side of the object to be processed and the laser beam irradiated to inside the injection hole is set to be reflected on the inclined plane and guided to the liquid column.
