摘要:<p>In a laser processing apparatus according to the present invention, an aberration compensating device (9) is provided between a beam section forming device (2) and a half mirror (1e) for making a focal point of visible light which is reference light and a focal position of infrared light which is laser beam coincided with each other. In the aberration correcting device, an aberration correcting convex lens (9a) having long focal length and a space portion (9b) are provided in a rotatable lens holder (9c). When observing an object to be processed (6), the lens holder is rotated to bring the space portion into an optical path, and is rotated to bring a convex lens for correction into the optical path when emitting laser beam. The laser beam is converged until incidence on the objective lens by the convex lens for correction to correct the aberration. As the aberration compensating device, a combination of a concave lens (9f) and a convex lens (9e) having different refractive indexes and the same focal length may be employed. Otherwise, a concave lens (10) may be provided to make a beam waist of the laser beam coincide with the portion to be processed. <IMAGE></p>
