Embodiment Construction

[0026]The intellectual insight of the present invention can be readily understood by considering the following detailed description with reference to the accompanying drawings, which are only illustrations. Next, while referring to the attached Figure 1 Embodiments of the present invention will be described. Where possible, the same symbol is assigned to the same part, and repeated descriptions are omitted.

[0027] refer to figure 1 , the laser processing apparatus of the present embodiment will be described. Such as figure 1 As shown, for the laser processing apparatus 1, it aligns the converging point P with the inside of the flat plate-shaped processing object S placed on the table 2, and irradiates the processing laser L1 (first laser light), This means that the modified region R due to multiphoton absorption is formed inside the object S to be processed. The platform 2 can move towards the up-down direction and the left-right direction and can rotate. The top of ...

Abstract

A machining laser beam is condensed to a position as close as possible to a specified position. A laser beam machining system comprising an object lens unit (5) including a machining object lens (42)for condensing a machining laser beam and a distance-measuring laser beam that measures the displacement of the main surface of a work to the same axial line, a light receiving unit (45) for receivingthe reflection light, off the main surface, of the distance-measuring laser beam, and an actuator (43) for holding the machining object lens (42) so as to be movable toward or from the main surface based on the received reflection light, and an enclosure (21) to which a laser unit for emitting a machining laser beam is mounted, the object lens unit (5) being detachably mounted to the enclosure (21).

Description

technical field [0001] The present invention relates to a laser processing device for processing an object to be processed by irradiating laser light. Background technique [0002] In the prior art laser processing technology, a measuring device (contact lens) for measuring the height of the main surface of the object to be processed is arranged in parallel at a predetermined interval with respect to the condensing lens for converging the laser light processed on the object to be processed. type displacement gauge or ultrasonic rangefinder, etc.) (for example, refer to FIGS. 6 to 10 in Patent Document 1 below). In this laser processing technology, when the laser is scanned along the main surface of the object to be processed, the measuring device is used to measure the height of the main surface of the object to be processed, and when the measurement point reaches directly below the condenser lens, according to For the measured value of the height of the main surface, the c...
